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.
