Question

Part B

What is the first time at which the mass of system A has maximum speed while traveling in the upward direction?

Express your answer using two significant figures.

Part C

What is the period of system B?

Express your answer using two significant figures.

Part D

What is the first time at which the mechanical energy of system B is all potential?

Express your answer using two significant figures.

Part E

If both systems have the same mass, what is the ratio kA/kBof their spring constants?

Express your answer using two significant figures.

ratio Ka/kB = ratio of their time period = 4/6 = 2/3 is the answer..
