A flat straight grass slide makes an angle of 28° with the horizontal and is 12 m long. A mat starts sliding from rest at the top of the slide. The mat has constant acceleration and it reaches a speed of 2.5s at the bottom of the slide.

A child of mass 45 kg goes down a playground slide of length 3.0 m that is inclined at an angle of 30° with respect to the horizontal. Find the speed of the child at the bottom given that the coefficient of kinetic friction between the child and the slide is 0.15 My main problem is reasoning through this type of problem. I solved for the components x-component=2.81m and y-component= 1.02 m. Then solved for fg=mg and its 441N. I...
