Question

A car of mass 800kg moving with a constant velocity 40km/h.Find the net force on it.
please solve the question in detail.... ....... mmm

Answer 1

The car is moving with a constant speed.
Thus, there is no acceleration is it.

Thus, the only force working on the car is the Normal Force, N =>

N = F = mg

F = 800 × 9.8

F = 7840 Newton.

Hope it was helpful.

Answer 2

Well, there is no force (except for the weight and normal) in the direction of displacement, and so the net force is zero.
