Question

A ball of mass 50g is thrown vertically upwards with a velocity of 20m/s and later caught by the thrower.

(a) Draw a velocity – time graph for the motion of the ball indicating the values of time.

(b) Determine the total distance traveled during its journey?

Answer 1

a)

b)

$$d=2h\\v^2=2gh\\ d=\frac{v^2}{g}\\d=\frac{20^2}{10}=40\ m$$
