There is a person, he strikes one end of a metal rod with a hammer. We have another person at the end of the rod feels a vibration in the rod 0.195 s before he hears the hammer strike the rod. If the temperature is 23◦C, how long is the metal rod? Use a bulk’s modulus of 106 GPa and a density of 5.69 g/cm3 .

The head of a golf club (of mass 250 g) is traveling at 44 m/s just before it strikes a 50 g golf ball (which is initially at rest). After the collision, the club head travels (in the same direction) at 36 m/s. a) Assuming momentum is conserved in the collision, find the speed of the golf ball just after the impact. (5 points) b) How much energy was lost in this collision? (5 points)

A 7.80-g bullet moving at 510 m/s strikes the hand of a superhero, causing the hand to move 5.90 cm in the direction of the bullet's velocity before stopping. (a) Use work and energy considerations to find the average force that stops the bullet. N (b) Assuming the force is constant, determine how much time elapses between the moment the bullet strikes the hand and the moment it stops moving. s
