Answer:
6.2m
Step-by-step explanation:
Maximum height is the height reached by an object launched into space before falling under the influence of gravity. Mathematically,
Maximum height (H) = u²sin²(theta)/2g
Given initial velocity (u) = 9m/s
Angle of launch = 60°
Acceleration due to gravity g = 9.8m/s
H = 9²(sin60)²/9.8
H = 81(0.8660)²/9.8
H = 6.2m
The maximum height reached by the ball is 6.2m
