Exam points

  • calculate translational kinetic energy or its change from an object’s mass and initial and final speeds
  • rearrange the kinetic-energy relationship to determine an unknown mass or speed
  • compare kinetic energies as mass or speed changes, including the squared dependence on speed
  • infer whether kinetic energy increases, decreases or stays constant from motion data
  • use measured mass, distance and time or speed data to determine kinetic energy experimentally

[Maximum number: 3]

(12 points, suggested time 25 minutes)
A student hangs a spring of unknown spring constant k vertically by attaching one end to a stand, as shown in Figure 1. The other end of the spring has a small loop from which small cylinders can be hung. In addition to the spring, the student has access only to a variety of cylinders of unknown masses, a stopwatch, and a digital scale.

Using the data in the velocity-time graph, calculate the change in kinetic energy of the cart from t=0.5 st=0.5 \mathrm{~s} to t=2.0 st=2.0 \mathrm{~s}. Show your steps and substitutions.
