A shopping cart with two nice kids, rolls off a horizontal roof ledge that is 50
meters high. The cart and nice kids land 30 meters from the base of the ledge.
How fast was the cart rolling when it left the ledge?
Answer:
9.39 m/s
Explanation:
Using the y-direction, we can solve for the time t it takes for the cart to reach the ground.
Assume the up direction is positive and the down direction is negative.
v₀ = 0 m/sa = -9.8 m/s² Δy = -50 m t = ?Find the constant acceleration equation that contains these four variables.
Δy = v₀t + 1/2at²Substitute known values into this equation.
-50 = (0)t + 1/2(-9.8)t²Multiply and simplify.
-50 = -4.9t²Divide both sides of the equation by -4.9.
10.20408163 = t²Square root both sides of the equation.
t = 3.194382825Now we can use this time t and solve for v₀ in the x-direction. Time is most often our link between vertical and horizontal components of projectile motion.
List out known variables in the x-direction.
v₀ = ?t = 3.194382825 s a = 0 m/s²Δx = 30 mFind the constant acceleration equation that contains these four variables.
Δx = v₀t + 1/2at²Substitute known values into the equation.
30 = (v₀ · 3.194382825) + 1/2(0)(3.194382825)²Multiply and simplify.
30 = v₀ · 3.194382825Divide both sides of the equation by 3.194382825.
v₀ = 9.391485505The cart was rolling at a velocity of 9.39 m/s (initial velocity) when it left the ledge.
Answer:
9.39 m/s

Multiply and simplify.
-50 = -4.9t²
Divide both sides of the equation by -4.9.
10.20408163 = t²
Square root both sides of the equation.
t = 3.194382825

A force of 20N acted on a ball thereby imparting an impulse of 70N's to the ball. For how long did the force act on the ball?
Answer:3.5 seconds
Explanation:
Gravitational force acts on all objects in proportion to their masses. Why then, a heavy object does not fall faster than a light object?
Answer:
Well, it's because the air offers much greater resistance to the falling motion of the feather than it does to the brick. ... Galileo discovered that objects that are more dense, or have more mass, fall at a faster rate than less dense objects, due to this air resistance. A feather and brick dropped together.

a speed swimmer love to race around the parks pine which is 25m around if she can swim 20 laps in 7200s what is her average speed?
Answer:
the average speed of the swimmer is 0.069 m/s.
Explanation:
Given;
complete distance around the park pine, d = 25 m
total lap completed, = 20 laps
time of laps completion, t = 7200 s
The total distance completed by the swimmer = 20 x 25 = 500 m
The average speed of the swimmer = distance / time
= (500 m) / (7200 s)
= 0.069 m/s.
Therefore, the average speed of the swimmer is 0.069 m/s.

I would give the BRAINLIEST for the best answers!!!
Answer:
It is important to have a range of tools that can measure all parts of the electromagnetic spectrum because electromagnetic spectrum have different radiations such as infrared, visible light, ultraviolet, radio waves, microwaves, X-rays and gamma rays. Each of these radiation requires different instrument for their measurement. So that's why a range of tools are needed to measure electromagnetic spectrum.
Which would most likely contain this same type of current? the air above a wildfire a carton of milk in a refrigerator a snowdrift on a shady mountainside a boulder in a hot desert
Answer: the air above a wildfire
Explanation:
First part of question is: The diagram shows currents that form as water is heated.
When water is being heated from below, convection currents are used. This happens when the molecules at the bottom are heated thus giving them energy and enabling them rise to the surface. The colder water at the surface will therefore sink to the bottom where is is heated making it rise as well and the process is repeated.
When a wildfire is ignited, the concept is the same. The air above the wildfire is the water in this scenario. It is heated at the bottom and rises thereby forcing the air above to come down and be heated as well. Both situations uses convectional currents.
Answer:
The air above a wildfire

A steam governor uses negative feedback to control the speed of a steam engine. Suppose a steam governor has two balls that are each rotating with a tangential speed of 3.7 m/s. The balls are 0.10 m from the rotation axis, and the centripetal force on each ball is 670 N. What is the mass of one of the balls? Pls help
Answer:
no lo se
Explanation:
Supposing a steam governor has two balls that are each rotating with a tangential speed of 3.7 m/s. The balls are 0.10 m from the rotation axis, and the centripetal force on each ball is 670 N. Then the mass of one of the balls is 4.89 kg.
What is Centripetal force ?''Centripetal force is force acting on a body performing circular motion, which is along radius of the circle and directed towards the center of circle"
since centripetal force acts at right angle to the tangential velocity of the body, there is no displacement in the direction of the force, hence no work done. It has newton(N) as Si unit.
centripetal force is given by,
F= mv²÷r
Where m is mass of the body
v is velocity of the body
r is radius of circle at which body is moving.
Given
velocity v = 3.7 m/s
radius r = 0.10 m
centripetal force F = 670N
mass = ?
from formula we can write,
670 = m(3.7)²÷0.10
m= (670×0.10)÷(3.7)²
m = 4.89 kg
Hence mass of one of the balls is 4.89 kg

-The phone call goes out, transmits through microwaves, then moves to the tower. Then the signals go to the nearest hub to the receiver of the call.
2.Which property of AM frequencies allow them to travel over long distances?
-high amplitude
-high energy
-constant velocity
-long wavelength
3.what types of waves do cell phones use?
-radio waves
-gamma rays
-microwaves
Answer:
1. The phone call goes out, transmits through radio waves, then moves to the central hub. Then the signals go to the nearest tower to the receiver of the call.
2. long wavelength
3. radio waves
Explanation:
1. A cell phone call is works basically as a two-way radio, consisting of a radio transmitter and a radio receiver. When you dial a call to a friend on your cell phone, your phone converts your voice into an electrical signal, which is then transmitted through radio waves. The radio waves then moves to the central hub. Then the signals go to the nearest tower. The network of cell towers then relays the radio wave to your friend’s cell phone, which converts it to an electrical signal and then back to sound again.
2. AM means amplitude modulation. In AM frequencies, sound signals are modulated by changing the amplitude or maximum height of radio waves. AM frequencies use longer wavelength radio waves than FM frequencies. Because of their longer wavelengths, AM waves reflect off a layer of the upper atmosphere called the ionosphere, and thus travel over longer distances than FM waves.
3. Cell phones use radio waves to communicate.
