Doing some physics homework and am kind of stumped here!
It is a sunny day, and we have decided to do lab outside instead of staying cooped up. Ceylani goes to the top of Jordan Hall, and throws a ball of mass 4.87 kg down from the top of Jordan which is 124 m tall. Her lab partner, Tray, is waiting at the bottom to collect the ball and return it, for more data trials. The ball has a speed of 3.8 m/s when Ceylani throws it straight down. What is the speed of the ball as it reaches the ground? Your Answer: units Answer
2) With a collision velocity V = 650 m/s, a 60-gram projectile collides and becomes embedded into a 30kg sand-filled box, which is initially at rest. Calculate the maximum deflection angle 0 and the total mechanical energy before and after the collision. 2m
7. According to a seated woman, a 67.7-kg man runs with his 32.4-kg dog toward a 20.2- kg child who is running toward the man. The man and dog's speed is 3.50 km/h, and the child's speed is 1.25 km/h. 1. According to the woman, what is the kinetic energy of the man-dog-child system? ( Ans: 48.5 J ) 2. According to the man, what is the kinetic energy of the man-dog-child system? ( Ans: 17.6 J )
2. A marksman holds a rifle of mass m = 3.00 kg loosely, so it can recoil freely. He fires a bullet of mass m = 5.00 g horizontally with a velocity relative to the ground of v=+ 300 m/s. What is the recoil velocity of the rifle? (Young and Freedman, 2012) BONUS: What is the total kinetic energy of the rifle and bullet after it was fired? Before Rifle + bullet After =?

Mike then takes his now 1175 kg car and crashes it at 50 m/s into the back of a 1600 kg Jeep traveling at 10 m/s. They roll off together going 18 m/s. How much work was done by the crumple zone of Mike’s car? Just a short simple answer will suffice.
Is the following statement true? If not, why? Within the system, both the momentum and kinetic energy are conserved during each of the collisions ( spring-loaded elastic, hoop spring, and putty collisions).
I. A lump of clay (m = 3.00 kg) is thrown towards a wall at speed v = 3.00 m/s. The lump sticks to the wall. (a) What kind of collision is it? Is momentum conserved during this collision? Why or why not? (b) Calculate the impulse imparted on the lump by the wall. (c) Calculate percent of initial kinetic energy lost during this collision. II. Same lump is thrown towards the same wall, but this time it bounces off the wall at speed of 3.00 m/s. (a) What kind of collision is it? Is momentum conserved during this collision? Why or why not?
