Part II

10. Elevate the right end of the track to an angle of 10. Add 50g to the mass hanger (total mass 100g)

11. Repeat steps 2-4 above.

12. Repeat step 7 above to compare the work and change of kinetic energy for the falling mass.

13. Calculate the work done by the tension force on the cart and the work done by the gravitational force on the cart (how far did it climb?). Compare the total work done on the cart to its change in kinetic energy.

14. Compare the change in gravitational potential energy of both the cart and the fallingmass to the change in the kinetic energy (of both the cart and the falling mass).
