During a bungee jump, a student (i) initially moves downward with increasing speed and then (ii) moves downward with decreasing speed, (iii) reaches the turnaround point (that is, the low point of the motion), (iv) moves upward with increasing speed, and finally (v) moves upward with decreasing speed. For each situation (i) through (v), state the direction of the bungee jumper's velocity and acceleration (that is, upward, downward, or zero).

Hobbyists build a compressed air powered cannon which is able to launch a pumpkin a horizontal distance of 2700 ft. Assuming no air resistance, and assuming the pumpkin is launched at ground level, what is the minimum initial speed of the pumpkin (just as it leaves the cannon) that is needed for it to reach this distance, in m/s? 294 X m/s

Just before it reaches the ground, is the final speed of the ball thrown upward (a) larger, (b) smaller, or (c) the same in magnitude, compared with the final speed of the ball thrown downward?
The driver of a car slams on the brakes when he sees a tree blocking the road. The car slows uniformly with an acceleration of 5.60 m/s2 for 4.20 s, making straight skid marks 62.4 m long, all the way to the tree. With what speed does the car then strike the tree?
During the siege of Constantinople that led to its conquest by the Ottomans in 1453, the Hungarian engineer Orban built a set of bombards (primitive cannon) to throw enormous stones at the city to breach its walls. The largest of these could throw a 300 kg stone a distance x = 2 km. Assume that the stone was launched at an angle of 0 = 45 degrees above the horizontal; in the absence of air resistance, this gives the largest range. a) What speed did the stone have to be launched at to achieve this range? b) How long was the ball in the air? c) How fast was the ball traveling at the apex of its flight?
