the ball takes 0.2 sec to travel the height of the window, which is 2 m.
then the speed of the ball at that time was
we know that:
where is the initial velocity.
then we have the equation for the position as a function of time.
= initial position
r = position as a function of time
= initial velocity
g = acceleration of gravity
t = time.
if the ball is thrown from the ground then:
= 0 m
we want to find now the distance between the window and the ground.
when the ball reaches the bottom of the window t = 1.8s
the window is 37,404 m high
finally, to know how high the ball rises we must know at what moment the vertical velocity of the ball is zero.
now we replace t in the position equation
the ball reaches up to 44.70 m in height.
