Problem 6-11 Dynamics with friction - B

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 \(mg\).)


We must choose \(x\) and \(y\)-axes. Which is best?
