A skier is initially at point A at 50 m (tA=0.0 minutes); he moves to the right in 1 minute to point B at 400.m (tB=1.0 minutes), then turns and moves 150. m to the left at point C after another minute (tC=2.0 minutes) and finally after another minute has moved right by 100. m at point D (tD=3.0 minutes). 1. What is the skier’s distance from A to D? 2. What is the skier’s displacement from A to D? 3. What is the skier average velocity from A to D? 4. What is the skier average speed from A to D

A seasoned mini golfer is trying to make par on a tricky number five hole. The golfer can complete the hole by hitting the ball from the flat section it lays on, up a 45∘45∘ ramp, over a moat, and into the hole which is ?=1.90 md=1.90 m away from the end of the ramp. If the opening of the hole and the end of the ramp are at the same height, ?=0.880 m,y=0.880 m, at what speed must the golfer hit the ball to launch the ball over the moat so that it lands directly in the hole? Assume a frictionless surface, so the ball slides without rotating. The acceleration due to gravity is 9.81 m/s2.
To start an avalanche on a mountain, an artillery shell is fired from 1250 m from the base of the mountain at 300 m/s, 55.0°. What are its coordinates 9.0 seconds later? Where does it hit on the mountain? If you are unable to answer, draw a diagram showing why.

Jim is driving his car at 32m/s (72mi/h) along a highway where the speed limit is 25m/s (55mi/h). A highway patrol car observes him pass and quickly reaches a speed of 36m/s. At that point, Jim is 300m ahead of the patrol car. How far does the patrol car travel before catching Jim?

A stone is thrown from the top of a tower 15m above ground level at time t = 0. At the instant of launch, the stone has a speed of u = 5.00 ms-1 and moves in projective motion at an angle of 30°.
