A block of unknown mass is attached to a spring with a spring constant of 5.00 N/m and undergoes simple harmonic motion by amplitude of 11.0cm. When the block is halfway among its equilibrium position and the end point, its speed is measured to be 28.0 cm/s.
a) Compute the mass of the block.
____________ kg
b) Compute the period of the motion.
____________ s
c) Compute the maximum acceleration of the block.
