Question

A monkey perched 20m high on a tree drops a coconut directly above your head as you run with a speed of 1.5 m/s beneath the tree. How far behind you does the coconut hit the ground? When should the monkey have dropped the coconut to hit?

Answer 1

20/9.8 = 2.0408 seconds to fall
2.0408 x 1.5 = 3.0612 m behind you, the coconut falls.
He should have dropped it 2.0408 seconds earlier
