A block of unknown mass is attached to a spring with a spring constant of 6.00 N/m and undergoes simple harmonic motion with an amplitude of 12.0 cm. When the block is halfway between its equilibrium position and the end point, its speed is measured to be 33.0 cm/s
a)Calculate the mass of the block.
b)Calculate the period of the motion.
c)Calculate the maximum acceleration of the block
I know how to do parts b and c but I need to have the mass correct before I can do them. Is it right to think that the 33cm/s value is the max velocity?
