A 0.1 kg body moves at a constant speed of 10 m/s. It is pushed by applying a constant force for 2 s. Due to this force, it starts moving exactly in the opposite direction with a speed of `4 m//s`. Then

Relative speed of two bodies moving in opposite direction with speed u and m/s .

A body of mass 10kg is moving with a constant velocity of 10m//s . When a constant force acts for 4 seconds on it, it moves with a velocity 2m//sec in the opposite direction. The acceleration produced in it is

An object of mass 10kg moves at a constant speed of 10 ms^(-1) . A constant force, that acts for 4 sec on the object, gives it a speed of 2ms^(-1) in opposite direction. The force acting on the object is :

A body of mass 0.40 kg moving initially with a constant speed of 10 m s^(-1) to the north is subject to a constant force of 8.0 N directed towards the south for 30 s. Take the instant the force is applied to be t = 0, the position of the body at that time to be x = 0, and predict its position at t = –5 s, 25 s, 100 s.
