Can anyone help with this?

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.)

Free runners jump long distances and land on the ground or a wall. how do they apply newton’s second law to lessen the force of impact?

Can anybody me with this? ? (picture included.)
