A machine gun mounted on a 2000 kg car on a horizontal frictionless surface fires 10 bullets per second. If 10 g be the mass of each bullet and 500

\mathrm{m}{\mathrm{s}^{ - 1}}

, the velocity of each bullet, then the acceleration of the car will be

View answer and explanation

Correct option: C

\frac{1}{{40}}\mathrm{m}{\mathrm{s}^{ - 2}}

Option C (

\frac{1}{{40}}\mathrm{m}{\mathrm{s}^{ - 2}}

) is correct because the acceleration is calculated by dividing the force exerted by the bullets on the car by the mass of the car.

. If the coefficient of restitution is 0.6 , the height to which the ball will rebound is A running man has the same kinetic energy as that of a boy of half his mass. The man speed up by

2\mathrm{\;m}{\mathrm{s}^{ - 1}}

and the boy changes his speed by

x = \mathrm{m}{\mathrm{s}^{ - 1}}

, so that the kinetic energies of the boy and the man are again equal. Then x in
