Solve A and B using energy considerations.

A) A 0.80 kg coconut is growing 10 m above the ground in a palm tree. The tree is just at the edge of a cliff that is 15m tall. What would the maximum speed of the coconut be if it fell to the ground at the base of the tree?

B) What would the maximum speed be if it fell from the tree to the bottom of the cliff?

Use the kinematic equation vf^2 = vi^2 + 2ad where;

vf = ?

vi = 0 m/s

a = 9.8 m/s^2

d1 = 10 m

d2 = 25 m

final velocity at the ground (d1) : vf = sqrt (2) (9.8) (10) = 14 m/s

final velocity to the bottom of the cliff (d2) : vf = sqrt (2) (9.8) (25) = 22.14 m/s
