Problem 6-11 Dynamics with friction - Part 2 - C

A child is sliding down a water slide inclined at \(25^\circ\) to the horizontal. The coefficient of kinetic friction between the child and the slide is \(0.10\). What is the magnitude of the acceleration of the child? (Hint: \(F_N\) is not equal to \(mg\).)

Accumulated Solution

FBD with all forces, directions and angles indicated.

Correct! All choices are permissible but this one gives the simplest solution.

The acceleration in the \(y\)-direction is:

(A)  \(g\)

(B)  \(-g\)

(C)  \(0\)
