If the kinetic energy of a body is increased by $300\%$,then the percentage change in momentum will be:

$A$ 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?

When the speed of a vehicle increases by $2 \ m/s$,its kinetic energy doubles. What is the original speed of the vehicle?

Two bodies of different masses $m_1$ and $m_2$ have the same kinetic energy. If $p_1$ and $p_2$ are their respective momenta,find the ratio $p_1 : p_2$.

If a lighter body of mass $M_1$ and velocity $V_1$ and a heavy body of mass $M_2$ and velocity $V_2$ have the same kinetic energy,then:

$A$ particle is dropped from a height $h$. $A$ constant horizontal velocity $u$ is given to the particle. Taking $g$ to be constant everywhere, the kinetic energy $E$ of the particle with respect to time $t$ is correctly shown in:
