3 3 A ball is thrown vertically up from the top of a building 20 m high with an initial velocity of 20 m / s. The displacement of the ball is measured from the point that the ball is thrown, with an upward displacement taken as positive. Which of the following graphs represents the displacement of the ball with time t? 4 A car moving at 40 km / h speeds up with constant acceleration for 3 minutes, reaching a final speed of 80 km / h. What is the distance travelled during this time? A 3.0 km B 6.0 km C 180 km D 360 km 5 An object of mass M travelling to the right with velocity 2v collides with another object of mass 2M travelling to the left with velocity v. It can be assumed there are no energy transfers from the objects to the surface they are moving on and to the surrounding air. Which statement is true about both objects during the collision? A The inertia of each object changes. B The sum of the total energy in their stores decreases. C They experience a deceleration of the same magnitude. D They experience a force of the same magnitude.

4 6 A car is travelling on a flat road with constant velocity. It can be assumed that there is negligibl
