Answer:
Thus, the maximum height is 7.35 m.
Explanation:
initial velocity, u = 12 m/s
acceleration due to gravity, g = 9.8 m/s^2
Velocity at maximum height, v = 0 m/s
Let the maximum height is h.
Use third equation of motion
[tex]v^{2}=u^{2}-2 g h\\0 = 12\times 12 - 2 \times 9.8\times h\\h =7.35 m[/tex]
