Answer:
(a) S = 1.8m
(b) F = 23.9N
Explanation:
The solution to this problem requires the knowledge of the concepts of constant acceleration motion for part (a) and newton's second law for part(b).
(a) s =(u + v)/2 ×t
(b) F = m(v-u)/t
u = 0m/s because the pitcher starts to throw the ball from rest

Answer:
Explanation:
Given
For first case
launch angle
at highest point
For second case
at highest Point velocity is
as there is no acceleration in x direction therefore horizontal velocity is same
