138702 A rocket motor consumes $100 \mathrm{~kg}$ of fuel per second exhausting it with a speed of $5 \mathrm{~km} / \mathrm{s}$. The speed of the rocket when its mass is reduced to $\frac{1^{\text {th }}}{20}$ of its initial mass, is (Assume initial speed to be zero and ignored gravitational and viscous forces.)
138703 Consider a spherical planet which is rotating about its axis such that the speed of a point on its equator is $v$ and the effective acceleration due to gravity on the equator is $\frac{1}{3}$ of its value at the poles. What is the escape velocity for a particle at the pole of this planet.
