A professional golfer crushes a golf ball off the tee a horizontal distance of 310 m (see photo). The ball leaves the tee at an angle of
45° with respect to the horizontal. If the head of the driver is in contact with the 45-g ball for 1.0 ms, calculate the average force
exerted on the ball by the driver.

42. ● A 1200-kg car is moving at 20.0 m/s due north. A 1500-kg car is moving at
18.0 m/s due east. The two cars simultaneously approach an icy intersection
where, with no brakes or steering, they collide and stick together. Determine
the speed and direction of the combined two-car wreck immediately after the
collision. Example 8-7
1. A 3 N baseball moving left toward the batter with a velocity of 15 m/s is struck with a bat which causes it
to move in a reversed direction with a velocity of 30 m/s. Calculate the average force exerted on the ball if
the bat is in contact with the ball for 0.01 s.

- Review. A 60.0-kg person running at an initial speed of 4.00 m/s jumps onto a 120-kg cart initially at rest (Fig. P9.37). The person slides on the carts top surface and finally comes to rest relative to the cart. The coefficient of kinetic friction between the person and the cart is 0.400. Friction between the cart and ground can be ignored. (a) Find the final velocity of the person and cart relative to the ground. (b) Find the friction force acting on the person while he is sliding across the top surface of the cart. (c) How long does the friction force act on the person? (d) Find the change in momentum of the person and the change in momentum of the cart. (c) Determine the displacement of the person relative to the ground while he is sliding on the cart. (f) Determine the displacement of the cart relative to the ground while the person is sliding. (g) Find the change in kinetic energy of the person. (h) Find the change in kinetic energy of the cart.

Suppose a fairly large asteroid that has a mass of 5.001012 kg (about a kilometer across) strikes the Moon ata speed of 15.0 km/s.

Such an event may have been observed by medieval English monks who reported observing a red glow and subsequent haze about the Moon. (c) In October 2009, NASA crashed a rocket into the Moon, and analyzed the plume produced by the impact. (Significant amounts of water were detected.) Answer part (a) and (b) for this real-life experiment. The mass of the rocket was 2000 kg and its speed upon impact was 9000 km/h. How does the plume produced alter these results?arrow_forward
