Which type of force is shown in the image?

Answer:

T=35,000J/5000W=7s

Answer:

The answer is 6.3

Explanation:

[tex]f \: = \: m(kg) \times g( \frac{n}{kg} )[/tex]

[tex]f \: = \: 630 \times {10}^{ - 3} \times 10 = 6.3[/tex]

The normal force acting on a body is the weight by gravitational pull of earth. The force acting on the hanging mass of 630 g is 6.17 N.

Force is an external agent acting on a body to deform it or to change it from the state of rest or motion. Force is a vector quantity having both magnitude and direction.

A  normal force acting on a body is due to its weight by gravitational pull of earth. The force of gravitation is a kind of force by which an object attracts other objects into its centre of mass. The strength of force depends on the mass of the object.

The weight of an object in earth is the product of its mass and gravity. The acceleration due to gravity on earth is 9.8 m/s². Therefore, the force by weight of the hanging mass of 630 g or 0.630 Kg is :

0.63 × 9.8 m/s² = 6.17 N.

Answer:

The acceleration of the motorbike as it came to a stop was -8.78 m/s² (NOTE: Negative sign indicates deceleration)  

Explanation:

From the question,

A motorbike is traveling to the left with a speed of 27.0 m/s.

This is the initial speed, that is, initial speed = 27.0 m/s

Also, from the question,

The rider slams on the brakes and the bike skids 41.5 m, that is, the bike covers a distance of 41.5 m after the rider slams on the brakes.

Distance = 41.5 m

To determine the acceleration of the motorbike as it came to a stop,

Since, the bike came to a stop, then, the final speed is 0 m/s

From one of the equations of motion for linear motion

v² = u² + 2as

Where v is the final speed (velocity)

u is the initial speed (velocity)

a is the acceleration

and s is the distance

From the question

v = 0 m/s

u = 27.0 m/s

s = 41.5 m

Putting these into the equation

v² = u² + 2as

0² = 27.0² + (2×a×41.5)

0 = 729.0 + 83a

83a = -729.0

a = -729.0 / 83

a = -8.78 m/s² (NOTE: Negative sign indicates deceleration)  

Answer:

8.8 m/s^2

Khan Academy answer

Distance between Davien's school and beach, D = 50 km.

Also, Davian's house is 10 km closer to the beach than the school.

So, distance between Davien's house and beach, d = 40 km.

Speed of Davian, s = 40 km/h.

Now, time taken is given by :

[tex]t =\dfrac{Distance}{Speed}\\\\t=\dfrac{40}{40}=1\ hour[/tex]

Therefore, Davien reach the beach at 1 : 30 P.M .

Hence, this is the required solution.

Answer:

The displacement of the man has a magnitude of 40 m

Explanation:

Distance and Displacement

A moving object constantly travels for some distance at defined periods of time. The total distance is the sum of each individual distance the object traveled. It can be written as:

dtotal=d1+d2+d3+...+dn

This sum is obtained independently of the direction the object moves.

The displacement only takes into consideration the initial and final points of the path defined by the object in its moving. The displacement, unlike distance, is a vectorial magnitude and can be even zero if the object starts and ends the movement at the same point.

The man walks around half the circumference and ends up at the opposite side of the circled shape. Taking into consideration only the starting and ending points, the man's displacement is a vector whose magnitude is the diameter of the circle, thus:

The displacement of the man has a magnitude of 40 m

Answer:

I = 1.4 [amp]

Explanation:

To solve this problem we must use ohm's law, which tells us that the voltage is equal to the product of the current by the resistance.

Therefore:

V = I*R

where:

V = voltage = 14[V]

I = current [amp]

R = resistance = 10 [ohm]

I = 14/10

I = 1.4 [amp]

v = 6m/2.3 s

v=2.61 [tex]\frac{m}{s}[/tex]

Answer:

[tex]\boxed {\tt v\approx2.61 \ m/s}[/tex]

Explanation:

Velocity can be found by dividing the displacement by the time.

[tex]v=\frac{d}{t}[/tex]

The displacement is 6 meters and the time is 2.3 seconds.

[tex]d= 6 \ m\\t= 2.3 \ s[/tex]

Substitute the values into the formula.

[tex]v=\frac{6 \ m}{2.3 \ s}[/tex]

Divide.

[tex]v=2.60869565 \ m/s[/tex]

Let's round to the nearest hundredth. The 8 in the thousandth place tells us to round the 0 to a 1.

Answer:

work = 1125 [J]

Explanation:

To solve this problem we must remember the definition of power, which is defined as the relationship between work and time. The power can be calculated using the following equation:

Power = work/time

Power = 12.5 [w]

work = joules [J]

time = 1.5 [min] = 90 [s]

work = 12.5*90

work = 1125 [J]

Answer:

a) s = 5619.2 m

b) v = 456.5 m/s

Note: The preceding question is given below:

An airplane flying horizontally with a speed of 500 km/h at a height of 800 m drops a crate of supplies (see the following figure). If the parachute fails to open, how far in front of the  release point does the crate hit the ground?

Explanation:

From the preceding question;

height, h = 800 m,

speed of plane = 500 km/h = 500000 m / 3600 s = 139 m/s

Speed of projectile = 139 m/s + 300 m/s = 439 m/s

a) using h = ut + 1/2 * gt² = 1/2 gt² (sice u = 0)

t = √(2h/g) where g = 9.8 m/s²

t = √(2 * 800/9.8)

t = 12. 8 s

horizontal distance, s = horizontal velocity * time

s = 439 * 12.8

s = 5619.2 m

b) Final vertical velocity v₂ = u - gt

v₂ = 0 - 9.8 * 12.8 = 125.4 m/s

horizontal velocity, vₓ = 439.0 m/s

resultant velocity, v = √(v₁² + vₓ²)

v = √{(125.4)² + (439.0)²}

v = 456.5 m/s

Answer:

Force of friction = 14 pound

Explanation:

Magnitude = Force / Weight

Magnitude = 14 / 188

Magnitude = 0.074

So,

Force of friction = 14 pound

Force of friction is same as forcee

Frictional force along the direction of motion = 14 pounds

Frictional force is  the resistance force towards relative motion. Frictional Force is a force the equation for which is given by the equation

[tex]f = \dfrac{\mu}{N} \\\mu = Coefficient \; of \; Friction \\\\N = Normal \; Reaction[/tex]

Weight of the  Castco shopping  cart = 188 Pounds (lb)

Force required to push the cart = 14 Pounds

Uniform velocity of shopping cart = 1.1 m/s

Acceleration in the direction of motion of cart = 0 m/s

So we can say that the forces in direction of motion must be balanced

So the  magnitude (absolute value) of the frictional force along the direction of motion

= 14 pounds

Answer:

Acceleration occurs when an object changes its VELOCITY or DIRECTION or both.

Explanation:

Answer:

When the velocity of an object changes it is said to be accelerating. Acceleration is the rate of change of velocity with time. ... Acceleration occurs anytime an object's speed increases or decreases, or it changes direction. Much like velocity, there are two kinds of acceleration: average and instantaneous. answer velocity or direction.

=> x = 50°

Answer:

50°

Explanation:

Step 1:

52° + 78° + x = 180°       Sum of a Δ
