Question 1

A 242 g box slides up a 16.1° ramp at a speed of 4.05 m/s. Using conservation of energy and assuming the ramp is frictionless, how far along the ramp does the box slide before stopping?

0.745 m
3.02 m
29.6 m
0.871 m

Question 2

A 10800 kg jet is preparing to land on a military aircraft carrier. In order to do so, the pilot manoeuvres the jet's tail to hook and snag a cable that is attached to a spring with spring constant 71200 N/m. If the spring stretches 33.0 m to stop the jet, what was the jet's landing speed?

218 m/s
14.7 m/s
84.7 m/s
120. m/s

Question 3

You are lawn bowling and bowl a ball with a speed of 5.23 m/s. Unfortunately, your ball hits a large rock of mass 310 g, resulting in a perfectly elastic collision. If the final velocity of the ball after the collision is -2.42 m/s, what must the mass of the ball be?

0.114 kg
0.844 kg
0.424 kg
1.18 kg

A box (with a penguin inside) with mass, M, slides down a frictionless ramp, starting a height H above ground level. At the lowest point of the ramp (height = -0.1H) it slides through a curved section of track with radius, R= 0.25H. The box (w/ penguin) then rises to ground level (height = 0) and at that point, leaves a jump at an angle θ. At the highest point of its trajectory, h2, it strikes a blob of glue...
