An automobile vehicle has mass of 1,500 kg. What must be the force between vehicle and the road if vehicle is to be stopped with negative acceleration of ` 1.7 ms^(-2)`?

Two persons manage to push a motor car of mass 1,200 kg at uniform velocity on the road. The same motor can be pushed by three persons to produce an acceleration of 0.2 ms^(-2) . With what force does each person push the motor car ?( Assume that all persons push motor car with same muscular effort.)

A car travelling at a speed of 20 ms^-1 applies brackes and stops within 10s. What is the acceleration of car?

m_1 and m_2 are the masses of two bodies. When a force of 5 N is applied on each body, m_1 gets an acceleration of 10 m//s^2 and m_2, 20 m//s^2. If the two bodies are tied together and the same force is applied, find the acceleration of the combined system.

What force is required to produce an acceleration of 2ms^-2 on a body of mass 10 kg?

A vehicle travels half the distance L with speed V_1 and the other half with dspeed v_2 , then its average speed is

A flywheel of mass 30 kg has a radius of 0.2 m .What force should be applied tangentially to the rim of the flywheel so that it acquires an angular acceleration of 23 rad//s^2 ?
