Question

A monkey throws a banana horizontally from the top of a tree. The banana hits the ground 3.03 seconds later and lands d = 30.9 meters from the base of the tree.

1. What was the resultant velocity of the banana as it hit the ground?
magnitude = ? m/sec.
2. What is the angle ?° from the horizontal?

Answer 1

horizontal speed is constant: 30.9/3.03 m/s

The vertical speed is v = at = -4.9t

The angle x is such that tan(x) = Vy/Vx

Answer 2

Oops -- v = -9.8t
