Q.
The ratio of momentum and kinetic energy of particle is inversely proportional to the time. Then this is the case of a:
Work, Energy and Power
Solution:
For uniformly accelerated motion particles momentum is given as $p=$ mat and its kinetic energy is given as $K=(1 / 2) m a^{2} t^{2}$ and the ratio of the two is $p / K=2 / a t$.
