c)
mg = kx
0.5* 9.8 = 1706.317 x
x = 2.87 mm
======
2.
a)
since springs are arranged in parallel so equivalent constant = 2k
2 *k = F/x = 86.2* 9.8 / 0.0657 = 12857.84 N/m
k = 6428.92 N/m
b)
angular frequency
w = 2pi / T = 2pi / 2.04 = 3.08 rad/s
sqrt (k/m) = w
12857.84 / m = 3.08^2
m = 1355.4 Kg
now, M = 1355.4 - 86.2 = 1269.2 kg
c)
f = 1/T = 1/2.04 = 0.49 Hz
d)
t = 10 * 2.04 = 20.4 s
