A child's toy consists of a small wedge that has an acute angle θ. The sloping side of the wedge is rough with a coefficient of static friction of μS. A puck of mass m on the wedge remains at constant height such that the distance from the bottom of the wedge to the puck remains at L as the wedge spins at a constant speed as shown at right. The wedge is spun by rotating, as an axis, a vertical rod that is firmly attached to the wedge at the bottom end.
a) What is the direction of puck's velocity? _______________________
b) If the speed of rotation is constant, what is the direction of puck's acceleration? ______________
c) If the speed of rotation is increasing, what is the approximate direction of puck's acceleration?
d) Give the radius of the puck's track in terms of known quantities. __________________________
e) Assume that the speed is constant and it is so HIGH that the puck is at the verge of sliding "out."
On the figure given below at left, draw all the forces acting on the puck. Then draw a clear and complete FBD on the coordinate system given below at right. Verify that your FBD is accurate before moving to part (f).
