a force 4000 n accelerates a car of mass 800 kg from rest to 20 ms how far does the car travel while the force is acting?​

d = 40 m

Explanation:

Given that,

Force, F = 4000 N

Mass of a car, m = 800 kg

Initial velocity, u = 0 (at rest)

Final velocity, v = 20 m/s

We need to find the distance traveled. Force acting on a car is given by :

F = ma

Where

a is the acceleration of the car.

Let it has traveled d distance. Using third equation of motion.

So, the required distance is equal to 40 m.

the part of the wave he is travelling on is the crest

thermal energy is the answer
