Suppose a slide similar to Der Stuka is 36.0 meters high, but is a straight slope, inclined at 45° with respect to the horizontal.

(a) Find the speed of a 51.1 kg thrill seeker at the bottom of the slide, assuming no friction.

26.5 m/s

(b) If the thrill seeker has a speed of 22.6 m/s at the bottom, find the change in mechanical energy due to friction.

-4978 J

(c) Find the magnitude of the force of friction, assumed constant.

____ N

2. Relevant equations/attempts

Magnitude of F = W/change in X, but no X is given, just Y.

I know F= mu/N and I found normal force to be [51.1 kg*9.8 m/s^2 cos(45)]=354 N

I am stuck there and cannot think of a way to calculate mu.
