HELP!!
I need extra help. I'm studying for my Final Exam which is tomorrow and I cannot remember how to find forces of objects on an inclined plane. The question I'm having troubles with is:
A 12.5 kg crate is placed on a ramp that is at an angle of 22 degrees from the horizontal. Find the acceleration of the crate would be down the ramp:
a) in the absence of friction (answer 3.67 m/s-squared down slope)
b) if the coefficient of kinetic friction is 0.0 (0.95 m/s-squared down slope)
Help!!

Resolve g into its component || and Perp to the inclined surface

u will have gsin(theta) & gcos(theta) along || and perp to inclined surface respectively
