A 250 g air-track glider is attached to a spring with springconstant 4.0 N/m. Th damping constant due to air resistance is0.015 kg/s. The glider is pulled out 20cm from equilibrium and released. How many oscillations will it make during the time which the amplitude decays to e-1 of tis initial value?

33.33 seconds

Explanation:

= Initial length pulled = 20 cm

b = Damping constant = 0.015 kg/s

k = Spring constant = 4 N/m

m = Mass of glider = 250 g

Time period is given by

Using exponential decay formula

Final amplitude = Initial times decay

The time taken is 33.33 seconds

the independent variable, or the one that is intentionally manipulated is the speed.

i don't understand. explain it clearly
