If $p$ is the linear momentum of an object and $v$ is its velocity,write the formula for its kinetic energy.

The momentum of an object increases by $50\%$. By what percentage will its $K.E.$ increase?

$A$ ball of mass $2\,kg$ and another of mass $4\,kg$ are dropped together from a $60\,ft$ tall building. After a fall of $30\,ft$ each towards the earth,their respective kinetic energies will be in the ratio of:

If momentum is increased by $20 \%$, then kinetic energy increases by (in $\%$)

The work done by a force on a body of mass $5 \,kg$ to accelerate it in the direction of the force from rest to $20 \,m/s$ in $10 \,s$ is:

The kinetic energy of a body decreases by $36\%$. The decrease in its momentum is ............... $\%$
