A 990 g block oscillates on the end of a spring whose force constant is k = 66 N/m. The mass moves in a fluid which offers a resistive force F = -bv, where b = 0.162 N·s/m.
(a) What is the period of the motion?
_________s
(b) What is the fractional decrease in amplitude per cycle?
__________
(c) Write the displacement as a function of time if at t = 0, x = 0, and at t = 1.00 s, x = 0.120 m.
x = (_______ m )
exp(________ s-1t )
sin (_________ s-1t)
