(a) To find the maximum height reached by the ball, we can use the kinematic equation:
where:-
is the maximum height,-
is the initial velocity,-
is the angle of projection,-
is the acceleration due to gravity.Given:-
-
-
Substituting the values:
So, the maximum height reached by the ball is approximately
.(b) To find the range (horizontal distance) of the ball when it touches the ground, we can use the kinematic equation:

Substituting the values:
So, the range (horizontal distance) of the ball when it touches the ground is approximately
