A ball of mass m is shot straight up into the air with an initial speed vj. (a) What is the maximum height reached by the ball (in terms of vj and g)? (b) A second ball is dropped from rest from a height, h, directly above the first ball, and is released at the same time that the first ball is shot upwards. At what height will the two balls collide? Provide an expression in terms of h, Vị, and g. (c) From what height should the second ball be dropped from so that the two balls collide when the first ball is at its maximum height?
In the absence of air resistance, if a ball is thrown vertically upward with a certain initial speed, on returning to its original level it will have the same speed. When air resistance is a factor, will the ball be moving faster, the same, or more slowly than its throwing speed when it gets back to the same level? Why? (Physicists often use a “principle of exaggeration” to help them analyze a problem. Consider the exaggerated case of a feather, not a ball, because the effect of air resistance on the feather is more pronounced and therefore easier to visualize.)
Suppose a car manufacturer tested its cars for front-end collisions by hauling them up on a crane and dropping them from a certain height. What height corresponds to a collision at 55 km/hkm/h ? Express your answer to two significant figures and include the appropriate units. What height corresponds to a collision at 110 km/hkm/h ? Express your answer to two significant figures and include the appropriate units.

You're driving along at 25m/s with your aunt's valuable antiques in the back of your pickup truck when suddenly you see a giant hole in the road 55 m ahead of you. Fortunately, your foot is right beside the brake and your reaction time is zero! If the coefficients of friction are μs =0.6 and uk =0.3, how much time does it take you to stop if you don't want the antiques to slide and be damaged?
Julie, who has a mass of 65 kg, is enjoying a day at the local water park with some friends. She waits for her turn at the top of a water slide and then begins sliding down. The topof the water slide is 12 m above the pool and the bottom is 1 m above the pool. How fast is she moving when she reaches the bottom, in m/s? (Round your answer to one decimal place if necessary.)
A baseball is thrown vertically upward with an initial velocity of 9 m/s. Neglecting air friction, how long will it take to return to its original position?
James Bond runs then jumps off a building in a horizontal direction at speed v. He tries to reach the roof of a building nearby, at a distance d = 10 m. (a) That building is 10 m shorter than the one where Bond jumps off. If his speed cannot exceed 10 m/s and his initial velocity is purely horizontal, does he have a chance to make it? If yes, what is his minimum requiredspeed? (b) Consider instead what happens if the building he jumps to has the same height as the one he jumps from but this time he jumps with some initial angle q. If his initial speed is 10 m/s, does he have a chance to make it? If yes, for what range of q is this possible?
Io, a satellite of Jupiter, is the most volcanically active moon or planet in the solar system. It has volcanoes that send plumes of matter over 500 km high. Due to the satellite's small mass, the acceleration due to gravity on Io is only 1.81 m/s2and Io has no appreciable atmosphere. Assume that there is no variation in gravity over the distance traveled. a)What must be the speed of material just as it leaves the volcano to reach an altitude of 380 km? b)If the gravitational potential energy is zero at the surface, what is the potential energy for a 33 kg fragment at its maximum height (500 km) on Io? c)How much would this gravitational potential energy be if it were at the same height (500 km) above earth?
A car traveling at 35 m/s suddenly runs out of gas while driving up a 7° incline. How long will it take for the car to stop after it runs out of gas (if it doesn't use its brakes and there is no friction)? How far will it travel before it stops?
A toad with mass of 280 g leaps into the air to catch a fly. If the toad's jump was at an angle of 35 degrees with respect to the horizontal, and with an initial velocity of 5.1 m/s, what is its speed (in m/s) when it reaches its maximum vertical displacement?
