# 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

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

The acceleration in the $y$-direction is:

(A)  $g$

(B)  $-g$

(C)  $0$
