Physics springs practice problems
2 kg 1) A 2-kg mass on a frictionless surface is attached to a spring. It is at rest when it is a) The mass completes 5 oscillations in 8 seconds. What is the force constant of the spring? b) At what time t is the mass 3 cm to the right of the equilibrium point? c) What is the maximum speed of the mass? Where is it when it has its maximum speed? m = 0 x pulled to the right a distance xmax = 10 cm and then released from rest at time t = 0. 2 kg 1) (continued) A 2-kg mass on a frictionless surface is attached to a spring. It is at rest when it is d) At what time t is the velocity of the mass 0.2 m/s [R]? e) Where is the mass when its velocity is 0.2 m/s [R]? Use two different methods to determine this. m = 0 x
