Question

a wodden cube having mass 10kg is dropped from the top of building after 1 sec a bullet of mass 20g fired at it from the ground hits the block with v of 1000m/sec at an angle of 30 degree to the horizontal moving upward and gets embendede un the block the velocity of block/bullet system immediately after the collision is

Answer 1

A wodden cube having mass 10kg is dropped from the top of building after 1 sec a bullet of mass 20g fired at it from the ground hits the block with v of 1000m/sec at an angle of 30 degree to the horizontal moving upward and gets embendede un the block the velocity of block/bullet system immediately after the collision is :

Solution :-

Mass of the wooden cube = 10 kg

Total time taken buy bullet = 1 sec

Mass of the bullet = 20 g

Velocity = 1000 m/sec

Angle of the bullet = 30°

___________________________

Formula used :-

m1 u1 = m2 u2 = ( m1 + m2 ) v

The velocity = -400 m/ sec
