Unformatted text preview: www.clas.ucsb.edu/staff/vince/ 5) An Air track cart attached to a spring completes one oscillation every 2.4s. At t=0 the cart is released from rest at a distance of 0.10m from its equilibrium position. Draw a graph of position vs. time and determine the position of the cart at (a) 0.60 s b) 3.0s? Also indicate on your graph where the kinetic and potential energies are at their minimum and maximum values. 6) When a 0.420 kg mass is attached to a spring, it oscillates with a period of 0.350s. If instead a different mass, m 2 , is attached to the same spring, it oscillates with a period of 0.700s. Find (a) the force constant of the spring and (b) the mass of m 2 . 7) When the length of a simple pendulum is tripled, what happens to the period of its oscillation? a) The period decreases to 1/3 of the original period. b) The period does not change. c) The period increases by a factor of 3. d) The period increases by a factor of 3....
