A steel ball of mass m = 1 kg and a cord of negligible mass and
length L = 2 m make up a simple pendulum that can pivot without
friction about the point O (see below). This pendulum is released
from rest in a horizontal position and when the ball is at its
lowest point it strikes a block of mass m = 1 kg sitting at rest on
a shelf. Assume that the collision is perfectly elastic and...
A bullet of mass 4.3 g is fired horizontally into a 7.4 kg wooden block at rest on a horizontal surface. The coefficient of kinetic friction between block and surface is 0.53. The bullet stops in the block, which slides straight ahead for 1.7 m (without rotation). (a) What is the speed of the block immediately after the bullet stops relative to it? (b) At what speed is the bullet fired?
