Question

An object is attached to a coiled spring. The object begins at its rest position att o seconds. It is then propelled downward Write an equation for the distance of the object from its rest position after t seconds, if the amplitude is 3 inches and the period is 4.5 seconds. The equation for the distance d of the object from its rest position is (Type an exact answer, using as needed. Use integers or fractions for any numbers in the equation ) Enter your answer in the answer box and then click Check Answer All parts showing

Explanation / Answer

amplitude = 3 inches

period = 4.5 seconds

2pi/b = 4.5

b = 2pi/4.5

b = 4pi/9

equation is

y = - 3 sin ( 4pi/9) t
