Two bodies of masses $m_1$ and $m_2$ are moving with the same kinetic energy. If $P_1$ and $P_2$ are their respective momenta,the ratio $\frac{P_1}{P_2}$ is equal to:

$A$ particle is initially at rest on a frictionless horizontal surface. $A$ force of constant magnitude and direction is applied to it. The graph shows the work done $(W)$ on the particle versus its speed $(v)$. If no other horizontal forces act on the particle,what should the graph look like?

The kinetic energy of an object decreases by $19\%$. What is the percentage decrease in its momentum?

Kinetic energy $(K)$ depends on momentum $(P)$ as $K = \frac{P^2}{2m}$. Which of the following graphs is/are correct?

$A$ particle is released freely from a height $H$. At a certain height,its kinetic energy is two times its potential energy. Then,the height and the speed of the particle at that instant are respectively ($g=$ acceleration due to gravity).

If the linear momentum of a body is increased by $50 \%$,then the kinetic energy of that body increases by (in $\%$)
