**1. The problem statement, all variables and given/known data**

A horizontal force of 200 n is required to cause a 15 kg block to slide up a 20degree incline with acceleration of 25 cm/s^2. Find the friction force on the block and the coefficient of friction.

ANSWERS:

Friction force = 134N

Coefficient of Friction = 0.65

**2. Relevant equations**

Ff = u Fn

**3. The attempt at a solution**

I can't figure out where to begin.

I'm not sure if it's relevant, but I found:

Fg to be 147.15 N

horizontal component to be 50.33 N

Vertical component to be 138.28N
