A bullet of mass 10 g travelling horizontally with a velocity of
150 m s-l strikes a stationary wooden block and comes to rest
in 0.03 s. Calculate the distance of penetration of the bullet
into the block. Also calculate the magnitude of the force exerted
by the wooden block on the bullet.
5. An object of mass 1 kg travelling in a straight line with a velocity
of 10 ms- collides with, and sticks to, a stationary wooden
block of mass 5 kg. Then they both move off together in the
same straight line. Calculate the total momentum just before
the impact and just after the impact. Also, calculate the velocity
of the combined object.
6. An object of mass 100 kg is accelerated uniformly from a velocity
- of 5 m s-1 to 8 m s-1 in 6 s. Calculate the initial and final
momentum of the object. Also, find the magnitude of the force
exerted on the object.
