Question

evaluate if the weight is moving upwards downwards or neither when t=1
then solve for st
than s1
Explanation / Answer
s(0) = -1
P = 1.2
2pi/ b = 1.2
b = 2pi/ 1.2
b = 5pi/4
-1 = a (1)
a = -1
hence, s(t) = -1 cos (5pi/4) t
weight is moving upwards when t = 1
s(1) = -1 cos (5pi/4 * 1 )
s(1) = 0.8
