## Homework Statement

A Ball is dropped onto a step at point A and rebounds with a velocity Vo at an angle 15 degrees with the vertical. Determine the value of V

_{0}knowing that just before the ball bounces at Point B its velocity V

_{B}forms an angle of 12 degrees with the vertical.

## Homework Equations

X = Vt

Y = Vt - 0.5gt

^{2}

## The Attempt at a Solution

X = (VoSin15)t

Y = (VoCos15)t -0.5gt

^{2}
