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 µs = 0.40 and µk = 0.30,respectively.The puck's initial speed is 63 m/s.What vertical height does the puck reach above its starting point?

Question

Quizplus · Accepted Answer

The correct answer is A because the puck will reach a vertical height of 130 cm above its starting point. This can be calculated using the following equation:h = (v^2 * sin^2(theta)) / (2 * g * (µk * cos(theta) + sin(theta)))where:h is the vertical height reached by the puckv is the initial speed of the pucktheta is the angle of the rampg is the acceleration due to gravityµk is the coefficient of kinetic friction
