A high-speed photograph of a club hitting a golf ball is shown in the figure below.
The club was in contact with a ball, initially at rest, for about 0.0024 s. If the ball has a mass of 55 g and leaves the head of the club with a speed of 1.9 x 102 ft/s, find the average force (in kN) exerted on the ball by the club.
kN
Two ice skaters stand together as illustrated in Figure (a). They "push off" and travel directly away from each other, the boy with a velocity of v = +0.42 m/s. If the boy weighs 718 N and the girl 450 N, what is the girl's velocity after they push off? (Consider the ice to be frictionless.)

- A baseball player hits a bunt during which the bat is in contact with the ball for 0.0005 s. If the bat applies a force of 3,000 N to the 0.15 kg baseball, what is the change in the ball's velocity? Your answer should be in units of m/s but you should only submit the number for your answer (and don't worry about negative signs, just use a positive value).arrow_forwardThe club was in contact with a ball, initially at rest, for about 0.0014 s.

- Two ice skaters stand together as illustrated in Figure (a) below. They "push off" and travel directly away from each other, the boy with a velocity of v = 0.760 m/s to the left. If the boy weighs 715 N and the girl weighs 480 N, what is the girl's velocity (in m/s) after they push off? (Consider the ice to be frictionless.)arrow_forwardMost of us know intuitively that in a head-on collision between a large dump truck and a subcompact car, you are better off being in the truck than in the car. Why is this? Many people imagine that the collision force exerted on the car is much greater than that exerted on the truck. To substantiate this view, they point out that the car is crushed, whereas the truck is only dented. This idea of unequal forces, of course, is false; Newton's third law tells us that both objects are acted upon by forces of the same magnitude. The truck suffers less damage because it is made of stronger metal. But what about the two drivers? Do they experience the same forces? To answer this question, suppose that each vehicle is initially moving at 8.30 m/s and that they undergo a perfectly inelastic head-on collision. Each driver has mass 70.0 kg. Including the masses of the drivers, the total masses of the vehicles are 800 kg for the car and 4,000 kg for the truck.
