1. An ultra light plane with a compass bearing of due North has a speed of 60 km/hr relative to the air which is blowing due East at 30 km/hr. Which vector below best represents the velocity of the ground as seen by the pilot?

2. An ultra light plane with a compass bearing of due North has a speed of 60 km/hr relative to the air, which is blowing due East at 30 km/hr. The pilot throws an apple core from the plane at an angle, as seen by the pilot of 60 o East of North with a speed of 36 km/hr. Which vector below best represents the velocity of the apple core relative to the ground?

3. A car is travelling around the horizontal track shown on the right. What is the best choice for the direction of the acceleration of the car at points 1, 2, 3? I. If the car is travelling at constant speed? II. If the car starts from rest and is speeding up? III. If the car is slowing down?

4. A ball follows the trajectory on the left, where the vector at the start represents the initial velocity. Which vector below best represents the ball’s instantaneous velocity at the position 2?

5. A piece of ice slides from rest down a frictionless roof and onto the ground below. Which statement concerning the accelerations of the ice before and after it leaves the roof is most correct? (a) the accelerations have the same direction and magnitude (b) the accelerations have the same direction but different magnitudes (c) the accelerations have different directions but the same magnitude (d) the accelerations have different directions and different magnitudes.
