(a) Suppose a hockey puck slides down a frictionless ramp with an acceleration of 5.60 m/s2. What angle does the ramp make with respect to the horizontal?
°
(b) If the ramp has a length of 5.50 m, how long does it take the puck to reach the bottom?
s
(c) Now suppose the mass of the puck is doubled. What's the puck's new acceleration down the ramp?
m/s2
