Answer:
15 m/s
Explanation:
Speed(m/s) = distance(m)/time(s)
distance = 216 km = 216,000 m
time = 4 hours = 14,400 s
speed = 216000/14400 = 15 m/s
Answer:
A damped oscillation means an oscillation that fades away with time while Forced oscillations occur when an oscillating system is driven by a periodic force that is external to the oscillating system.
Explanation:
Damping is the reduction in amplitude (energy loss from the system) due to overcomings of external forces like friction or air resistance and other resistive forces. ... When a body oscillates by being influenced by an external periodic force, it is called forced oscillation.

Answer:
30
Explanation:
Assuming the velocity is 3π radians <em>per second</em>, the top will spin through an angle of ...
(3π radians/s)(20 s) = 60π radians
Since each revolution is 2π radians, that is ...
(60π radians)/(2π radians/revolution) = 30 revolutions
