When responding to sound, the human eardrum vibrates about its equilibrium position. Assume an eardrum is vibrating with amplitude of 6.70 x 10-7 meter and a maximum speed of 2.83 x 10-3 m/s.
(a) Estimate the frequency of the eardrums vibration?
Hz
(b) Estimate what is the maximum acceleration of the eardrum?
m/s2
A student is skateboarding down a ramp that is 8.99 m long and inclined at 24.1 ° with respect to the horizontal. The initial speed of the skateboarder at the top of the ramp is 4.77 m/s. Neglect friction and find the speed at the bottom of the ramp.
