## Homework Statement

A stone is thrown down a slope. I am given the Range of the slope and the max height from spot thrown.

R= 50m

h= 12m

## Homework Equations

I need to determine the magnitude of Vo and inital theta.

## The Attempt at a Solution

First I need to find V_o:

I feel that the only relevant portion to find the initial velocity is from the spot thrown to the max height where V_yo is 0. I broke up the components of velocity so that:

V_xo=vcos(theta)

V_yo=vsin(theta)

However, I'm lost after this because I don't know t. My first idea was to find t, but I was having problems finding an equation that doesn't use v, theta, in a time equation.

My second idea was to find an equation that avoids time such as v_y^2=V_yo^2-g(y-yo).

I haven't attempted the initial theta part yet.
