Question
Superman (m 50 kg) is running to save the day! He needs to reach the top of a circular curve
(R = 5 m). Superman notices that there is a sled sitting at rest a distance Az = 5 m from the
bottom of the curve. On the flat surface, the coefficient of friction between the surface and the
sled is
Mk=
-0.2. On the curve, there is no friction between the curved surface and the sled. See
the figure below denoting these values.
Ar= 5m
5kg
H=0.2
R = 5m
K=0
Part (a) Suppose Superman is approaching the sled with a superhuman constant velocity of 10
m/s. He then jumps onto the sled, such that they move as a single object. What is their final
velocity? Remember that velocity is a vector quantity!
