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?

Expert Answers

You need to use the following equation to find the vertical height such that:

`v_i = sqrt(2*a*h) => v^2_i = 2*a*h => h = (v^2_i)/(2a)`

`h_v= h*sin 30^o`

d represents the vertical height

a represents the acceleration of the hockey puck...
