        A ball is thrown vertically upward. Assume air resistance is negligible.

        Which of the following graphs shows how the vertical component of the velocity vv varies with time t from when the ball is thrown to just before it hits the ground?

        Four velocity-time graphs A-D for a ball thrown vertically upward.
A: Graph starts at positive v and decreases linearly
B: Graph is at a constant negative v for entire time
C: Graph starts at negative v, gradient increases until 0, then gradient decreases after 0
D: Graph is at a constant positive v for half the time, then is at a constant negative v for the other half

          A boat moves in a straight line for 8 seconds. The velocity–time graph for the boat is shown.

          A velocity–time graph with velocity in metres per second on the vertical axis from minus 3 to 7 and time in seconds on the horizontal axis from 0 to 8.5. A single straight line starts at 6 metres per second at time zero, decreases steadily, crosses the time axis at 6 seconds and reaches minus 2 metres per second at 8 seconds.

          Which row of the table shows the final displacement and velocity of the boat?

          Displacement / m

          Velocity / m s-1
