Slanted Surfaces with Friction: a 200 G Hockey Puck Is

question 6

Multiple Choice

Slanted surfaces with friction: 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 hockey puck and the metal ramp are μ_s = 0.40 and μ_k = 0.30, respectively. The puck's initial speed is 4.9 m/s. What speed does it have when it slides back down to its starting point?

• A) 2.8 m/s
• B) 3.5 m/s
• C) 4.2 m/s
• D) 4.9 m/s
