Roger the Rooster speeds up from 0 m/s to 2.5 m/s. If he covers 7.5 meters during this time, what was his acceleration in m/s/s?​

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.)

What is the average speed of a car that travels 40 mph for 1 hour and 60 mph in another hour?

Which situation will produce the greatest change of momentum
