## Homework Statement

An 0.80-kg cart rolls down a 30.0° hill from a

vertical height of 0.50 m. The distance that the cart must roll to the bottom of

the hill is 0.50 m/sin 30.0°=1.0 m. The surface of

the hill exerts a frictional force of 5.0 N on the cart.

Does the cart roll to the bottom of the hill?

## Homework Equations

I do know what equation to use or how to get the problem started.

f=ma

## The Attempt at a Solution

F=9.8m/s^2(.8kg)

F=7.84N(sin30)

F=3.92N

so it doesn't over come the frictional force.
