A child’s toy consists of a small wedge that
has an acute angle of 36◦. The sloping side
of the wedge is frictionless, and the wedge is
spun at a constant speed by rotating a rod
that is ﬁrmly attached to it at one end.
When the mass of 35 g rises up the wedge
a distance 20 cm and stays there, what is the
speed of the mass? The acceleration of gravity
is 9.8 m/s^2.
Answer in units of m/s.
