Get Help on Forces - Calculate Fn, Ff, Accel & Coeff of Friction

[emoprimokid]

i have some work i need help on any help would be awesome ;)

1. a toy sled is on a ramp with an angle of 25 degrees. It has a mass of 1.0 kg and mu=.25. calculate the Fn, Ff, and acceleration



2. a ramp is at an angle of 30 degrees. a crate on that ramp is 200.0kg. calculate the coeffcient of static friction
