# Frictions

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

block is placed on a ramp at an angle of 39.4 and height of the ramp is 1.610m and the mass of the block is 8.54kg

if coefficient of kinetic friction is 0.111 and the coefficient of static friction is 0.173 what is the speed of the block at the bottom of the ramp. if it started from the rest at the top of the ramp

magnitude of the net force on the block half way down the ramp

**2. Relevant equations**

Dont know how to approach these questions

which equations would be most appropriate?
