Two people, Ruiqian and Mia are on a merry-go-round moving at uniform speed. Ruiqian is a distance d from the center of the merry-go-round and Mia is a distance 2d. How does Ruiqian's linear speed vR comapre to Mia's linear speed vM?

If the temperature were raised very high, classically what would we expect the heat capacity per object to be for this one-dimensional system? give a numerical value. chigh t = __ j/k/object (one reason for the discrepancy is that the high-temperature limit assumes that the number of oscillators is large (n > > 1), which is not the case in this tiny system.)

After a big snowfall, you take your favorite rocket-powered sled out to a wide field. the field is 195 m across, and you know that your sled accelerates at a rate of 3.65 m/s2 when the rocket is on. how much time will it take the sled to cross the field starting from rest, assuming the rocket is on the whole time?
