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 63 m/s.What vertical height does the puck reach above its starting point? A)130 m B)270 m C)200 m D)66 m

Question

The correct answer is A because the puck will reach a vertical height of 130 m above its starting point. This can be calculated using the following equation:$$h = \frac{v^2 \sin^2 	heta}{2g(μ_k \cos 	heta + \sin 	heta)}$$where:* h is the vertical height reached by the puck (in meters)* v is the initial speed of the puck (in meters per second)* θ is the angle of the ramp (in degrees)* g is the acceleration due to gravity (in meters per second squared)* μ_k is the coefficient of kinetic friction between the puck and the ramp
