Hope this helps a little
initial distance up = 2
initial velocity component up = 9 sin 60 = 7.79
v = 9 sin 60 - 9.8 t
when v = 0, we are there
9.8 t = 7.79
t = .795 seconds to top
h = 2 + 7.79(.795) - 4.9(.795^2)
Answer:
6.2m
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
