Please help ASAP with the following problems:

Conceptual Questions: 1) Explain in terms of impulse how padding reduces forces in a collision. State this in terms of a real example, such as the advantages of a carpeted vs. tile floor for a daycare center. 2) Can objects in a system have momentum while the momentum of the system is zero? Explain. 3) What is the difference between an elastic and an inelastic collision? Give an example of an inelastic collision and explain how you know it cannot be elastic. 4) What is a perfectly inelastic collision? Describe an example of a perfectly inelastic collision. Textbook Problems: none My Problems: 5) In a typical golf swing, the club is in contact with the ball for about 0.0010 s. If the 45 g ball acquires a speed of 67 m/s, estimate the magnitude of the force exerted by the club on the ball. (3020 N) 6) a) Find the magnitude of the impulse delivered to a soccer ball when a player kicks it with a force of 1250 N. Assume the player's foot is in contact with the ball fro 5.95x10" s. b) If the mass of the ball is 0.43 kg and the ball starts from rest, what would its final speed be? (a: 7.4 N, b: 17 m/s) 7) A 92 kg astronaut and a 1200 kg satellite are at rest relative to the space shuttle. The astronaut pushes on the satellite, giving it a speed of 0.14 m/'s directly away from the shuttle. 7.5 seconds later the astronaut comes into contact with the shuttle. What was the initial distance from the shuttle to the astronaut? (13.7 m) 8) A 732 kg car stopped at an intersection is rear-ended by a 1720 kg truck moving with a speed of 15.5 m/s. If the car was in neutral and its brakes were off, so that the collision is approximately elastic, find the final speed of both vehicles after the collision. (t: 6.24 m/s, c: 21.7 m/s) 9) A 10.0 g bullet is fired into a stationary block of wood having a mass m = 5.00 kg. The bullet imbeds into the block. The speed of the bullet plus wood combination immediately after the collision is 0.600 m/s. What was the original speed of the bullet? (301 m/s) 10) A cart of mass m moves with speed v on a frictionless air track and collides with an identical cart that is stationary. If the two carts stick together after the collision, what is the final kinetic energy of the system? (mv /4)
