Homework Statement
A child goes down a playground slide with an acceleration of 1.40 m/s2. Find the coefficient of kinetic friction between the child and the slide if the slide is inclined at an angle of 29.0 degrees below the horizontal.
Homework Equations
Normal force = force of gravity (f_g) cos theta
F_f kinetic = mu_k . normal force
The Attempt at a Solution
here weight of the child is not given. so could someone help me how to approach such problem?
Thanks in advance
