Friction on Inclines

“A 2.0 kg block is placed on an inclined plane with an angle of 20°. The coefficient of kinetic friction between the block and the plane is 0.30. Calculate the acceleration of the block down the incline. Show your work. A wooden crate slides down an inclined ramp set at an angle of 35°. The coefficient of kinetic friction between the crate and the ramp is 0.15. Calculate the acceleration of the crate down the ramp. Show your work.”
