A pendulum is swinging with a frequency of 6.24 Hz. What is the time required for the pendulum to move from its equilibrium position to its point of maximum displacement? Select one: O a. 5.34 x 10-25 O b. 4.01 x 10-25 O c. 2.00 x 10-25 O d. 2.67 x 10-25A mass of 7.50 kg is attached to a spring with a spring constant of 1.80x 103 mm 50 that is oscillates on a horizontal frictionless surface. If the amplitude of the oscillation is 15.0 cm, then the magnitude of the maximum acceleration of the mass is mlsz. (Record your threedigit answer here in units of mlszi)
