1. A golf ball of mass 0.045 kgkg is hit off the tee at a speed of 35 m/sm/s . The golf club was in contact with the ball for 3.3010³ ss .Find the impulse imparted to the golf ball. Find the average force exerted on the ball by the golf club.

2. A 82-kgkg fullback is running at 3.5 m/sm/s to the east and is stopped in 0.85 ss by a head-on tackle by a tackler running due west. Calculate the original momentum of the fullback. Calculate the impulse exerted on the fullback. Calculate the impulse exerted on the tackler. Calculate the average force exerted on the tackler.

3. A ball of mass 0.295 kgkg that is moving with a speed of 5.1 m/sm/s collides head-on and elastically with another ball initially at rest. Immediately after the collision, the incoming ball bounces backward with a speed of 3.5 m/sm/s . Calculate the velocity of the target ball after the collision. Calculate the mass of the target ball.

4. A 28-gg rifle bullet traveling 200 m/sm/s embeds itself in a 3.7-kgkg pendulum hanging on a 2.5-mm-long string, which makes the pendulum swing upward in an arc. Determine the vertical component of the pendulum's maximum displacement. Determine the horizontal component of the pendulum's maximum displacement.

5.A 960-kgkg sports car collides into the rear end of a 2100-kgkg SUV stopped at a red light. The bumpers lock, the brakes are locked, and the two cars skid forward 2.8 mm before stopping. The police officer, estimating the coefficient of kinetic friction between tires and road to be 0.80, calculates the speed of the sports car at impact. What was the speed sports car at impact?

6. A gun fires a bullet vertically into a 1.40-kgkg block of wood at rest on a thin horizontal sheet. If the bullet has a mass of 23.8 gg and a speed of 230 m/sm/s , how high will the block rise into the air after the bullet becomes embedded in it?
