Question 1
An object in SHM with a period of 11.139 s has a maximum velocity of 1.323 m/s. What is the amplitude (see sheet 6)?

How To Solve

Question 2
An object in SHM has a maximum velocity of 24.48 m/s and an amplitude of 0.5913 m. What is the magnitude of the maximum acceleration (see sheet 6)? Indicate with a positive (negative) sign whether the acceleration as a function of time can (cannot) be written as -(2/T)2x, where x is the displacement as a function of time and T is the period.

Question 3
A spring is compressed by 12.61 cm when a 7.778 N force is exerted. What is the spring constant (see sheet 14)? Indicate with a positive (negative) sign whether the spring is stretched by the same (a different) amount when a 7.778 N tension acts on it.
