355673 Assertion :
The change in kinetic energy of a particle is equal to the work done on it by the net force.
Reason :
Work energy theorem is valid for a system of particles also

355674 A body of \(2\;kg\) mass is initially moving along a straight line with a velocity of \(1.5\;m{\rm{/}}s\). A force of \(4\;N\) is applied to it at an angle of \(60^{\circ}\) to the initial direction of motion. The change in its \(K.E.\) after the first second is

355675 In the figure shown initially spring is in unstretched state & blocks are at rest. Now 100 \(N\) force is applied on block \(A\) & \(B\) as shown in the figure. After some time velocity of \('A'\) becomes 2 \(m/s\) & that '\(B\)' 4 \(m/s\) & block \(A\) displaced by amount 10 \(cm\). Then work done by spring force on \(A\) will be:

355676 A body of mass \(m\) is in vertical motion under the influence of gravity then
