Final Exam Question Help!!! 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!!
