A spring of negligible mass stretches 2.20 cm from its relaxed length when a force of 10.50 N is applied. A 1.100 kg particle rests on a frictionless horizontal surface and is attached to the free end of the spring. The particle is displaced from the origin to x=5.0 cm and released from rest at t=0.
(c) What is the total energy of the system?

  • physics -

    total energy is spring, E=1/2 kx^2

    figure k, 10.5/.0022 N/m x=.05m
