consider a set-up similar to that in the write-up. Let the mass of the small, hanging mass be 10 g, and that of the glider 120 g. Let the air track make an angle of 0.35° with the horizontal. Assume that the hanging mass and glider are initially at rest. If the small mass drops a distance of 60 cm, how much potential energy does it lose (in joules or kg•m2/s2)? Although it is a loss of energy, please enter the answer as a positive number.
