**Need help with Incline Plane Problem!!**

## Homework Statement

A 10 kg block of ice slides down a ramp 20 m long, inclined at 10 degrees to the horizontal.

a) If the ramp is frictionless, what is the acceleration of the block of ice? (I was able to do this question the answer is 1.7 m/s²)

b) If the coefficient of kinetic friction is .10, how long will it take the block to slide down the ramp, if it starts from rest?

So right now I know I have...

m= 10 kg

d= 20 m

sin10

cos10

v1= 0 m/s

a= 1.7 m/s²

## Homework Equations

I'm really not sure what to do.

## The Attempt at a Solution

I'm not sure what to do, I need to know where to start!
