(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A brick is sliding down a ramp

Anet / acceleration = .5 m/s^2

m= 2 kg

M = the coefficient of friction = unknown or ?

3. The attempt at a solution

I'm just stuck on the last part

well first this is my work so far:

90-delta=

90 - 35 = 55

Fg= (2)(-9.8)

Fg= -19.6

Fg x = Fg cos (-) or -19.6 cos 55 = -11.2

Fg y = Fg sin (-) or -19.6 sin 55 = -16.1

Fn= 16.1

---------------

This is where i get stuck.

I don't know how to find M from here

please help me T-T
