Suppose a hockey puck slides down a frictionless ramp with an acceleration of 5.00 m/s2.
(a) What angle does the ramp make with respect to the horizontal?
(b) If the ramp has a length of 6.00 m, how long does it take the puck to reach the bottom?
(c) Now suppose the mass of the puck is doubled. What's the puck's new acceleration down the ramp?
Dizziness. Our balance is maintained, at least in part, by the endolymph fluid in the inner ear. Spinning displaces this fluid, causing dizziness, What is the radical acceleration (in m/s^2) of the endolymph fluid
