1. The problem statement, all variables and given/known data A 3.6 kg block slides down an inclined plane that makes an angle of 27 ◦ with the horizontal. Starting from rest, the block slides a distance of 2.4 m in 6.2 s. The acceleration of gravity is 9.81 m/s 2 . Find the coeﬃcient of kinetic friction between the block and plane. I've asked other friends for help but they couldn't figure it out.
