A 71 kg baseball player jumps straight up to catch a hard-hit ball. If the 140 g ball is moving horizontally at 28 m/s, and the catch is made when the ballplayer is at the highest point of his leap, what is his speed immediately after stopping the ball?

A 1500 kg car traveling at 12 m/s suddenly runs out of gas while approaching the valley shown in the figure. The alert driver immediately puts the car in neutral so that it will roll. What will be the car’s speed as it coasts into the gas station on the other side of the valley?
A 120-g toy car is propelled by a compressed spring that starts it moving. The car follows the curved track in the figure. What is the final speed in m/s and it coasts up to the frictionless slope, gaining 0.085 meters in altitude.
An archer shoots an 18.0-gram arrow at a 43.0-gram target on a wall 32.0 m high. If the arrow is shot at a velocity of v0 = 60.0 m/s, the speed of the arrow is 54.5 m/s when it reaches the target. If the arrow becomes embedded in the target and they both fly off the wall together, at what speed will they leave the wall? Should I use 60.0 m/s in the equation or 54.5 m/s: V’=(0.018)(60.0m/s)/ (0.061) -or- V’=(0.018)(54.5m/s)/ (0.061)
Dr. Jekyll (m = 70kg) is riding a skateboard when he realizes the cranberry juice he’s drinking is sweetened with artificial sweetener and turns into Mr. Hyde (m = 155kg). If Dr. Jekyll was initially moving at 6.5m/s, what is Mr. Hyde’s speed? (assume no external forces act)

A shooting star is actually the track of a meteor, typically a small chunk of debris from a comet that has entered the earth’s atmosphere. As the drag force slows the meteor down, its kinetic energy is converted to thermal energy, leaving a glowing trail across the sky. A typical meteor has a surprisingly small mass, but what it lacks in size it makes up for in speed. Assume that a meteor has a mass of 1.5 g and is moving at an impressive 50 km/s, both typical values. What power is generated if the meteor slows down over a typical 2.1 s? Can you see how this tiny object can make a glowing trail that can be seen hundreds of kilometers away?
