A 0.56-kg mass is suspended from a string, forming a pendulum. The period of this pendulum is 6.0 s when the amplitude is 1.5 cm. The mass of the pendulum is now reduced to 0.35 kg. What is the period of oscillation now, when the amplitude is 2.8 cm?

Since when is period dependent on mass or amplitude? Dont you have a lab to test the is exact hypothesis?

no this is a homework assignment from the textbook

There is no difference in the period because it the period is not dependent on mass or amplitude. (I just had this same problem on webassign)
