A 5.4 kg block slides down an inclined plane that makes an angle of 38 with the horizontal. Starting from rest, the block slides a distance of 2.5 m in 5.3 s. The acceleration of gravity is 9.81 m/s2 . Find the coefficient of kinetic friction be- tween the block and plane.

Two identical twins, Amy and Beatrice, are on top of two different slides, one on each slide. Both slides start 3 m above the ground and end 0.5 m above the ground. Amy's slide is a straight, 45 degree slide with height given by h=−x+3 (so it starts at x=0 with a height ...
