If an object has no kinetic energy,it cannot have momentum. Do you agree?

The masses of two substances are $4 \text{ g}$ and $9 \text{ g}$ respectively. If their kinetic energies are the same,then the ratio of their momenta will be

An athlete in the Olympic games covers a distance of $100 \ m$ in $10 \ s$. His kinetic energy can be estimated to be in the range

Two particles have masses $m$ and $4m$, and their kinetic energies are in the ratio $2:1$. What is the ratio of their linear momenta?

The kinetic energy of a body moving along a straight line varies with time as shown in the figure. The force acting on the body is:

$A$ bullet of mass $50 \ g$ is fired with a speed $100 \ m/s$ on a plywood and emerges with $40 \ m/s$. The percentage loss of kinetic energy is:
