363454 Assertion :
In case of bullet fired from gun(gun is of more mass), the velocity of bullet is more than velocity of gun.
Reason :
In firing, momentum is conserved.

363455 A machine gun of mass \(10\;kg\) fires \(20\;g\) bullets at the rate of 180 bullets per minute with a speed of \(100\;m{s^{ - 1}}\) each. The recoil velocity of the gun after \(1\,{\rm{sec}}\) is

363456 A 40 \(g\) ball dropped from a certain height bounces back from the horizontal ground without losing mechanical energy. If its speed is \(10\,m/s\) just before making contact with the ground, and the average value of the force of the ground on the ball is equal to 16 \(N\) while ball and wall are in contact, how long were they in contact?

363457 A projectile has a maximum range of \(25\;km.\) At the highest point of its motion, it explodes into two equal masses. One mass drops vertically downwards. The horizontal distance covered by the other mass from the time of explosion is (Take \(g = 10\;m{\rm{/}}{s^2}\))

363458 A ball falls towards the earth. Which of the following is correct? (Neglect the effect of planets & Sun)
