## Homework Statement

A person on a unicycle has a total weight of 900N. They need to climb to a height of one meter. If we build the ramp for a minimum pushing force of 50N, how long must the ramp be?

m=91.7kg

w=900N

F1=50N

Ry=1m

Rx=?

Rxy=?

θ=?

## Homework Equations

.5mv

^{2}=mgh

F1=mgsinθ

## The Attempt at a Solution

θ=arcsin(F1/mg)=3.18°

v=sqrt([itex]\frac{mgh}{2m}[/itex])=2.21m/s

I am not really sure at how to approach this problem. However, I have solved for the variables that I think are possible.
