A ball is projected vertically upwards with a speed of 10 m-s-t from point A,
which is at the top edge of a building. The ball hits the ground after 3 s. It is
in contact with the ground for 0,2 s and then bounces vertically upwards,
reaching a maximum height of 8 m at point B. See the diagram below. Ignore
the effects of friction.
8.1 Why is the ball considered to be in free fall during its motion?
B
8.2 Calculate the:
8.2.1 Height of the building
8 m
8.2.2 Speed with which the ball hits the ground
8.2.3 Speed with which the ball leaves the ground
-ground
aw a velocity versus time graph for the complete motion of the ball from A to B.
ow the following on the graph:
