A mass on a spring oscillates with a period of 0.8 s and an amplitude of 12 cm. At , it is 6 cm to the left of equilibrium and moving to the left. What is the position of the mass at time ?
A particle is moving along a straight line with simple harmonic motion. Its maximum acceleration is 10 ms−2 and its maximum speed is 3 ms−1. Calculate the amplitude of the motion.
A particle of mass 0.4 kg is moving along a straight line with simple harmonic motion. The distance between and a fixed point on the line is meters at seconds. The force acting on has a magnitude of and acts in the direction opposite to the motion. Find the period of the motion.
