A50 kg car is pushed so that it speeds up from 20 m/s to 50 m/s in 3 seconds. what is the force acting on the car?
a
500 n
b
0.2 n
c
10 n

A. 500 N

Explanation:

Acceleration is change in velocity over change in time.

a = Δv / Δt

a = (50 m/s − 20 m/s) / 3 s

a = 10 m/s²

Force is mass times acceleration.

F = ma

F = (50 kg) (10 m/s²)

F = 500 N

before we can answer, we have to see the choices that are printed there with the question.   that's the only way we can point you to the correct one.

answer: the correct answer is   air pressure at the top of mount everest is higher than at the bottom of the grand canyon.
