A downhill skier leaves the starting gate and accelerates down the hill. After 2.45 s she is travelling at a speed of 55 km/h. Determine (a) the rate of acceleration, (b) the distance travelled, (c) the angle of descent for the hill. (Ignore friction)

You are going 75 km/h along Laurelwood Drive when a police officer jumps out onto the road 42 m ahead of you to wave you down. It takes you 1.15 s to react and apply your brakes. What rate of acceleration must you have in order to stop before hitting the police officer? Is this a reasonable value? [HINT: Friction is limited by the weight of the car] STOP

A helicopter is ascending vertically at 4.3 m/s. At an altitude of 145 m above the earth a camera is dropped. (a) How long does it take until the camera hits the ground? (b) How fast is it travelling when it hits the ground? (c) If the camera was thrown horizontally at 2.5 m/s, how long does it take?

A snowboarder is travelling at 16.4 m/s when he takes a wrong turn and goes over a 156 m high cliff. How far will he travel before hitting the ground?
