1) A 25.0 gram projectile is fired at a velocity of 550 m/s toward a 3.4.0 kg block which is initially at rest. The projectile passes through the block and exits at a speed of 2.50 m/s. (a) What is the velocity of the block after the collision? (b) How much thermal energy is generated during the collision? (c) How much linear momentum is transferred during the collision? (d) Assuming that the collision lasts for an interval of 750 microseconds what is the average force acting between the projectile and the block during the collision? .n
