A bullet of mass 4.55 g moving with a velocity of 505 ms−1 strikes a wooden block of mass 2.95 kg which is suspended vertically from a long cord, as shown in the accompanying diagram. The bullet is embedded in the block and the two move off with the same velocity. Find : 3.1 the momentum of the bullet at the instant before it collides with the block; 3.2 the kinetic energy of the bullet at the instant before it collides with the block; 3.3 the velocity of the block at the instant immediately after the collision occurs 3.4 the maximum height through which the block swing
