A 70kg man runs at a pace of 4 m/s and a 50g meteor travels at 2 km/s. Which has the most kinetic energy?.
Answer:
the 70kg man
Explanation:
because he has more weight and is moving faster

The net force on a golf cart is 390 N north. If the cart has a total mass of 270 kg,
what are the magnitude and direction of the cart’s acceleration?
Answer:
1.4m/s^2 is the acceleration
Explanation:
magnitude and direction were already given . Using F=ma , acceleration is found .
The magnitude and direction of the cart's acceleration are 1.44 m/s² North.
To solve the given problem, we make use of newton's fundamental equation.
⇒ Newton's equation:
F = ma...................... Equation
⇒ Where:
F = Net force on the golf cartm = mass of the carta = acceleration of the cart.⇒ make "a" the subject of the equation
a = F/m............... Equation 2From the question,
⇒ Given:
F = 390 Nm = 270 kg⇒ Substitute these values into equation 2
a = 390/270a = 1.44 m/s² alone the direction of the force (North)Hence, the magnitude and direction of the cart's acceleration are 1.44 m/s² North.

Hi- I'm giving Brainliest for the best explanation to this.
If you were in a falling elevator, would you be able to jump up at the last second in order to survive? Please explain. I am so confizzled!
Thank you!
Answer:
yes it is possible, you have to lay down flat on your back
brainliest pweaseee
Answer:
Yes (and no)
Explanation:
Hey! This according to my theory is possible, the g-force of an object or "elevator" (in your explanation) is accelerating as it's gravitational pull is getting stronger. So it would but wouldn't be possible in a small elevator, because you-know it's an elevator (and of course you would bump your head, ouch!) ; p !
But if you had free or spare space to use, then you can jump upwards at the last second to cancel out the gravitational pull as if you actually (or originally) jumped from this height. But the gravitational pull may be too strong for those of humans, if the person acquiring and accelerating in G-Force doesn't have good leg muscle then he may be pulled along with the object by the gravitation.
I hope this helped! Pls Brainliest my answer! It would mean and help a lot! ; )

Ariel and Jackson are playing miniature golf. Ariel's ball rolls into a long, straight upward incline with a speed of 3.054 m/s and accelerates at -0.7762 m/s/s for 1.51 seconds until it reaches the top of the incline and then continues along an elevated section. Determine the length of the incline.
Answer:
The length is [tex]s = 3.73 \ m[/tex]
Explanation:
From the question we are told that
The speed is [tex]v = 3.054 \ m/s[/tex]
The acceleration [tex]a = -0.7762 m/s^2[/tex]
The time taken is [tex]t = 1.51 \ s[/tex]
Generally from kinematics equation the length of the inclined plane is mathematically represented as
[tex]s =ut + \frac{1}{2} * at^2[/tex]
=> [tex]s = 3.054 *1.51 + \frac{1}{2} * (-0.7762) *(1.51)^2[/tex]
=> [tex]s = 3.73 \ m[/tex]
what is the formula for calculating gravitational potential energy
Answer:
PEgrav = m *• g • h
Explanation:
In the above equation, m represents the mass of the object, h represents the height of the object and g represents the gravitational field strength (9.8 N/kg on Earth) - sometimes referred to as the acceleration of gravity.
Hope this helps
