List of top Physics Questions on momentum asked in KEAM

A ball of $200g$ mass moving with a speed of $5\,ms^{-1}$ collides with a wall and bounces back with the same speed. If the force exerted on the wall is $1N$, then the ball is in contact with the wall for:
A body of mass \(5\) kg collides with a wall with a speed of \(50\,\text{m s}^{-1}\) and rebounds with the same speed. If the time of contact of the body with the wall is \(\frac{1}{20}\) s, the force exerted on the wall is
The area under the curve drawn between the force \(F\) and time \(t\) is
If a ball of mass 0.02 kg bowled by a bowler straight to a batsman is hit back with the same speed with an impulse of 2 Ns, then the speed of the ball bowled is
A body of mass \(2\) kg is moving with a momentum of \(10\ \text{kg m s}^{-1}\). The force needed to increase its kinetic energy four times in \(10\) seconds is
CO$^{-}$ ion moving with kinetic energy of 20 keV dissociates into O$^{-}$ and C which move along the parent ion direction. Assuming no energy is released during dissociation, the kinetic energies of the daughters $(K.E.)_{O^-}$ and $(K.E.)_C$ are related as}
Water from a hose pipe of radius 5 cm strikes a wall normally at a speed of 5 m/s. The force exerted on the wall in newton is
If n bullets each of mass \(m\) are fired with a velocity \(v\) per second from a machine gun, the force required to hold the gun in position is
A ball of mass 10 g moving perpendicular to the plane of the wall strikes it and rebounds in the same line with the same velocity. If the impulse experienced by the wall is 0.54 Ns, the velocity of the ball is
A ball of mass 10 g moving perpendicular to the plane of the wall strikes it and rebounds in the same line with the same velocity. If the impulse experienced by the wall is 0.54 Ns, the velocity of the ball is
A ball of mass 10 g moving perpendicular to the plane of the wall strikes it and rebounds in the same line with the same velocity. If the impulse experienced by the wall is 0.54 Ns, the velocity of the ball is
