A 3.00 kg block of wood starting from rest slides down a 2.80 m wooden ramp

Question

 A 3.00 kg block of wood starting from rest slides down a 2.80 m wooden ramp that is inclined to an angle of 40 degrees. Because of a constant force of kinetic friction of 12.4 N acting on the block the entire descent, some of the block’s initial energy is transformed into thermal energy. Explain how you could solve this problem to determine the speed of the block at the bottom of the ramp as well as the coefficient of kinetic friction between the ramp and the block. Explain how the problem could be solved using words and/or diagrams.

Answer 1

So E M.,

That's three questions, at the same time, on the same subject topic, requiring generally the same skill set. With no indication that you've thought about the problems. Need I say more?

Perhaps I need: If you are at a loss on how to set up equations to these problems, please find someone to one-on-one tutor you for a bit at least. It's far more efficient than typing back and forth. Wyzant offers help at finding such, but anyone who has been through this intro physics material can perhaps spare you some time, if you ask politely?
