Question

A 2.5kg object oscillates at the end of a vertically hanging light spring once every 0.65s .

Part A

Write down the equation giving its position y (+ upward) as a function of time t. Assume the object started by being compressed 17cm from the equilibrium position (where y = 0), and released.

Write down the equation giving its position  ( upward) as a function of time . Assume the object started by being compressed 17 from the equilibrium position (where  = 0), and released.

	y(t)=(0.17m)?cos(2?t0.65s)
	y(t)=(0.17m)?sin(2?t0.65s)
	y(t)=(0.17m)?cos(0.65s?t)
	y(t)=(0.17m)?cos(t0.65s) Part B How long will it take to get to the equilibrium position for the first time? Express your answer to two significant figures and include the appropriate units. Part C What will be its maximum speed? Express your answer to two significant figures and include the appropriate units. Part D What will be the object's maximum acceleration? Express your answer to two significant figures and include the appropriate units. Part E Where will the object's maximum acceleration first be attained?   release point   equilibrium point
