To measure the speed of a bullet, the following situation is setup. A wooden block(m=0.50kg) is put on top of a fencepostwith a height of 1.5m. The bullet (m=.010kg) strikes theblock from a perfectly horizontal direction and remains embedded init. The block is measured to fall 1.6m from the base of thepost. How fast was the bullet going?
