Question

100m 1990B1 A bullet of mass m is moving horizontally with speed v when it hits a block of mass 100m that is at rest on a horizontal frictionless table as shown above The surface of the table is a height h above the floor After the impact the bullet and the block slide off the table and hit the floor a distance x from the edge of the table Derive expressions for the following quantities in terms of m h Vo and appropriate constants a the speed of the block as it leaves the table b the change in kinetic energy of the bullet block system during impact c the distance x Suppose that the bullet passes through the block instead of remaining in it d State whether the time required for the block to reach the floor from the edge of the table would now be greater less or the same Justify your answer e State whether the distance x for the block would now be greater less or the same Justify your answer
