Question

2).a truck starts from the rest and rolles down in a constant acceleration.it travella a distance of 400m in 20s.find the force acting on it if the mass is 7000kg.​

Answer 1

Answer:

Your answer is 14000 N

Explanation:

Here goes nothing

by the second eqn of motion we can say that

s=ut +1/2 at^2

therefore we get a=2m/s^2

Given Mass = 7000 kg

therefore F=ma

and F=7000 x 2

therefore F=14000 N
