Answer:
T = 2.82 seconds.
The frequency
Amplitude A = 25.5 cm
The maximum speed of the glider is
Explanation:
Given that:
the time taken for 11 oscillations is 31 seconds ;
SO, the time taken for one oscillation is :
T = 2.82 seconds.
The formula for calculating frequency can be expressed as :
The amplitude is determined by using the formula:
The limits that the spring makes the oscillations are from 10 cm to 61 cm.
The distance of the glider is, d = (61 - 10 )cm = 51 cm
Replacing 51 for d in the above equation
A = 25.5 cm
The maximum speed of the glider is:
where ;
