Answer:
Initial velocity = b) Height it reaches = 44.145 m
Explanation:
Using the first equation of motion we have
here
v is the final velocity
u is the initial velocity
a is the acceleration of the object
t is time
When the ball reaches it's highest point it's velocity will become 0 as it will travel no further
Also the acceleration in our case is acceleration due to gravity () as the ball moves in it's influence alone with '-' indicating downward direction
Thus applying the values we get
b)
By 3rd equation of motion we have
here s is the distance covered
Applying the value of u that we calculated we get
