speed is 5 m/s. The hill is 1 m high and 101 m long. what is

your speed at the bottom of the hill?

## Homework Equations

## The Attempt at a Solution

PE= mgh

(54)(9.8)(10)

= 5292

find the degree of the hill i think using tangent?

tan (10/100) ??

then solves for v

KE = 1/2 mv^2

Ik its something along those lines but I am a bit confused with the hill (do i use tangent, etc.) thank you very much, any help as soon as they possibly can is very much appreciated. thanks :-)
