Transcribed Image Text:

A 25 g bullet is fired horizontally, embedding itself into a 5 kg block of wood initially at rest on a horizontal rough surface. The block (with bullet embedded) slides along the surface, coming to rest at a distance of 65 cm from its original position. The coefficient of kinetic friction between the surface and the block of wood is 0.20 a) Calculate the velocity of the bullet- block combination after the bullet hit it. (2) b) Calculate the firing velocity of the bullet (1). c) The same bullet is then fired, at the same velocity as calculated in b). towards a ballistic pendulum of mass 6 kg. Calculate the maximum height the pendulum will reach after the bullet is inserted in it.
