U = 15 m/s
g = 9.8 m/s²
t = 2s
h = ut - 0.5gt²
⇒ h = 15×2 - 0.5×9.8×2²
⇒ h = 30 - 19.6
⇒ h = 10.4m

Potential Energy = mgh = 1.5×9.8×10.4 = 152.88 J

Initial velocity (u) = 15 m/s
Acceleration due to gravity (g) = 9.8 m/s²
Time taken (t) = 2s
Height (h) = ?

h = ut - 0.5 gt²
⇒ h = 15×2 - 0.5×9.8×2²
⇒ h = 30 - 19.6
h = 10.4m

Potential Energy (PE) = mgh = 1.5×9.8×10.4 = 152.88 J
