A 200 g hockey puck is launched up a metal ramp that is inclined at a 30 angle. The coefficients of static and kinetic friction between the puck and the ramp are s = 0.40 and k = 0.30,
 
  and the puck's initial velocity at the base is 3.8 m/s parallel to the sloping surface of the ramp. What speed does the puck have when it slides back down to its starting point?

Question 2

The capacitance per unit length of a very long coaxial cable, made of two concentric cylinders, is 50 pF/m.
 
  What is the radius of the outer cylinder if the radius of the inner one is 1.0 mm? (k = 1/40 = 8.99  109 N  m2/C2)
  A) 0.50 mm B) 4.0 mm C) 2.0 mm D) 3.0 mm E) 1.0 mm
