Q1. Using a M110 Sniper she fires 170 g bullet with the velocity of 820 m/s embeds itself into a 20.0 kg chunk of wood initially at rest on the edge of a 1.20 m high table. What type of collision is this? What is the velocity of the block/bullet immediately after impact? What is the x-distance the block/bullet travels while it hits the ground? What is an initial and final energy of the system energy? It takes .005 seconds for the bullet to embed itself into the block. What is an average impact force it experience?
