A cricketer catches a ball of mass 150 g in 0.1 s moving with speed 20 m/s, then he experiences a force of
- 300 N
- 30 N
- 3 N
- 0.3 N
Answer
(2) 30 N
Solution
Change in momentum: p = m v - 0 = 0.15 20 = 3 kg m/s
F = p t = 30.1 = 30 N
Answer: (2)

Answer: (2)
A 1 kg stationary bomb is exploded in three parts having mass 1 : 1 : 3 respectively. The parts having the same mass move in perpendicular directions with velocity 30 m/s, then the velocity of the bigger part will be
A body of mass 3 kg hits a wall at an angle of 60 and returns at the same angle. The impact time was 0.2 s. The force exerted on the wall is [figure]
Two masses as shown in the figure are suspended from a massless pulley. The acceleration of the system when masses are left free is [figure]
A mass of 1 kg is thrown up with a velocity of 100 m/s. After 5 seconds, it explodes into two parts. One part of mass 400 g comes down with a velocity 25 m/s. The velocity of other part is (Take g = 10 m s-2)
