Physics

To find out the height of the cliff, we can use the kinematic equation:
Vf² = Vi² + 2ad

Where,
Vi (initial velocity)  = 0m/s ( since it was dropped from rest)
Vf (final velocity) = 30m/s (impact velocity of 30m/s)
a (acceleration) = -9.8m/s² （negative sign because the direction is downward)
d (displacement) to be dete...
