Question

A 27 kg boy goes down a straight slide inclined 34◦ above the horizontal.
(a) List the forces acting on the boy. (You may disregard air resistance, but friction is not negligible.)
(b) Draw a free-body diagram of the boy.
(c) How large is the normal force of the slide on the boy?

Expert Solution

Step 1

Given data

Mass of boy is $m = 27 k g$

Angle of inclination is $θ = 34^{o}$

Acceleration due to gravity is $g = 9.80 {m/s}^{2}$

Unknowns:

Find the number of forces acting on the boy. Draw free body diagram and find the normal force.
