Answer:
It traveled 24 centimeters
Explanation:
The displacement of the object is equal to the area under the velocity vs time graph.
We can split this graph into two shapes, a triangle and a rectangle. So the total area is:
A = ½bh + wh
A = ½ (4 s − 0 s) (4 cm/s) + (8 s − 4 s) (4 cm/s)
A = 8 cm + 16 cm
A = 24 cm

Answer:
The speed of the football when it lift your hand is 8.86 m/s.
Explanation:
Given that,
Final speed of the football, v = 0.5 m/s
Height above the ground, s = 4 m
We need to find the speed of the football when it left your hand. The ball will move under the action of gravity. Using third equation of motion as:

So, the speed of the football when it lift your hand is 8.86 m/s. Hence, this is the required solution.
