3. A bullet of mass 0.20 kg is fired horizontally and embeds itself in a target of mass 2.50 kg. The target (with the bullet in it) flies off in the horizontal direction after being struck. What percentage of the bullet's incident kinetic energy does the target (with the bullet in it) carry off after being struck? (Neglect friction and air resistance.)

I. A lump of clay (m = 3.00 kg) is thrown towards a wall at speed v = 3.00 m/s. The lump sticks to the wall. (a) What kind of collision is it? Is momentum conserved during this collision? Why or why not? (b) Calculate the impulse imparted on the lump by the wall. (c) Calculate percent of initial kinetic energy lost during this collision. II. Same lump is thrown towards the same wall, but this time it bounces off the wall at speed of 3.00 m/s. (a) What kind of collision is it? Is momentum conserved during this collision? Why or why not? (b) Calculate the impulse imparted on the lump by the wall. (c) Calculate percent of initial kinetic energy lost during this collision. III. Same lump is thrown towards the same wall, but this time it bounces off the wall at speed of 2.00 m/s. (a) What kind of collision is it? Is momentum conserved during this collision? Why or why not? (b) Calculate the impulse imparted on the lump by the wall. (c) Calculate percent of initial kinetic energy lost during…

3. Two asteroids collide and stick together. The first asteroid has mass of 15 × 10³ kg and is initially moving at 770 m/s. The second asteroid has mass of 20 × 10³ kg and is moving at 1020 m/s. Their initial velocities made an angle of 20° with respect to each other. What is the final speed and direction with respect to the velocity of the first asteroid? How much thermal energy is generated in the collision?
