A particle is moving along a straight line with constant acceleration. At the end of tenth second its velocity becomes $20\, m/s$ and in tenth second it travels a distance of $10\, m$. Then the acceleration of the particle will be........$m/s^2$
$10$
$20$
$0.2$
$3.8$
A goods train accelerating uniformly on a straight railway track, approaches an electric pole standing on the side of track. Its engine passes the pole with velocity $u$ and the guard's room passes with velocity $v.$ The middle wagon of the train passes the pole with a velocity.
A particle moving with a uniform acceleration travels $24\, m$ and $64\, m$ in the first two consecutive intervals of $4\, sec$ each. Its initial velocity is......$m / \sec $
A bullet fired into a fixed target loses half of its velocity after penetrating $3\,cm$. How much further it will penetrate before coming to rest assuming that it faces constant resistance to motion?........$cm$
