Given that,
Angle = 53.1°
Speed = 22.2 m/s
Distance = 50 m
(a). We need to calculate the maximum velocity
Using formula of range
Put the value into the formula
(b). We need to calculate the time when the ball reaches the height
Using formula of time of flight
Put the value into the formula
Hence, (a). The maximum velocity is 35.0 m/s.
(b). The time when the ball reaches the height is 5.7 sec.
