1A ball is dropped from a height of 1.3 m. The graph shows how the height above the ground varies with time for several bounces.
At 2.6 s the magnitude of the displacement from the starting position is:
- AA 0.20 m
- BB 0.60 m
- Cc 0.70 m
- DD 1.30 m
2How can the velocity of the ball at time t = 2.5 s be determined from the graph?
- AA Calculate the area between the graph and the time axis up to t = 2.5 s.
- BB Divide the displacement at t = 2.5 s by 2.5 s.
- CC Divide the height at t = 2.5 s by 2.5 s.
- DD Draw a tangent to the graph at t = 2.5 s and calculate its gradient.
3A ball is thrown from position L and caught at position N.
L and N are the same height above the ground.
If vectors directed upwards are taken as positive, and air resistance is neglected, then the acceleration of the ball at L is -g and its speed is v.
Select the row of the table that correctly gives the acceleration and the speed of the ball as it reaches N.
- AA
- BB
- CC
- DD
4A box is dropped from a plane flying at a constant velocity and height.
Assuming that air resistance is negligible, as the box falls to the ground its horizontal position will -- AA remain unchanged
- BB lag behind the plane
- CC move ahead of the plane
- DD remain directly under the plane.
5A ball launcher fires a ball horizontally of a lab bench. The paths of the ball after two launches are shown in the diagram.
Which of the following quantities are different for the two launches?
- AA gravitational acceleration
- BB time of flight
- CC launch angle
- DD initial velocity
