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.
