355312 A quarter horse power motor runs at a speed of \(600\,rpm.\) Assuming \(40 \%\) efficiency, the work done by the motor in one rotation will be

355313 An object \({A}\) of mass 2\(kg\) is moving with a velocity of \({3 {~m} {~s}^{-1}}\) and collides head on with an object \({B}\) of mass 1 \(kg\) moving in the opposite direction with a velocity of \({4 {~m} {~s}^{-1}}\). After collision both objects coalesce so that they move with a common velocity \({v}\) equal to

355314 Two masses of 0.25 \(kg\) each moves towards each other with speed \(3\;m{s^{ - 1}}\) and \(1\;m{s^{ - 1}}\) collide and stick together. Find the final velocity

\(A\). Total energy of the ball and the earth remains the same
\(B\). Total momentum of the ball and the earth is conserved
\(C\). Momentum of the ball just after the collision is same as that just before the collision
