A 2.00-lb weight hangs motionless from a spring and is seen to stretch the spring 8.00 in. from its free length. It is pulled down an additional 1.00 in. and released. Write the equation of motion of the weight, taking zero at the original (motionless) position.
a) x = sin 0.433t
b) x = cos 6.95t
c) x = cos 0.433t
d) x = sin 6.95t
Thanks
