Homework Statement
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.
____ N2. Homework 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.
