## Homework Statement

A 50 kg mass is released from rest and begins to slide from the top of the incline (2.0 m). Th coefficient of kinetic friction between the mass and the inclines u

how much work does gravity do on the mass by the time it slides to the bottom of the ramp if the angle theta is 35 degrees?

## Homework Equations

W = f x d

F = m x a

W = (m x a) x d

## The Attempt at a Solution

First i found each following value:

m = 50

d = 2.0/sin(35 degrees)

a = 9.81 x sin(35 degrees)

Multiplied these all out, came with 981.

The answer the teacher says is 980 (he's a stickler to exact measurements)

something i did wrong?
