If the momentum of a body increases by $0.01\%$, its kinetic energy will increase by ........... $\%$
$0.01$
$0.02$
$0.04$
$0.08$
The kinetic energy acquired by a body of mass m is travelling some distance s, starting from rest under the actions of a constant force, is directly proportional to
A particle of mass $m$ at rest is acted upon by a force $P$ for a time $t.$ Its kinetic energy after an interval $t$ is
A body moving with speed $v$ in space explodes into two piece of masses in the ratio $1 : 3.$ If the smaller piece comes to rest, the speed of the other piece is
Two identical particles are moving with same velocity $v$ as shown in figure. If the collision is completely inelastic then
A body of mass $m$ is accelerated uniformly from rest to a speed $v$ in a time $T$. The instantaneous power delivered to the body as a function of time is given by
