A ball is launched horizontally from the top of a cliff with an initial velocity of 20 m/s. If the ball strikes the ground after five seconds, then (a) how high was the cliff and (b) how far from the base of the cliff will the ball land?

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.)

When a 5.0kg cart undergoes a 2.2m/s increase in speed, what is the impulse of the cart

However, had it been a real sound, the sound's pitch would have been increased by the doppler effect, since the falcon was moving the source of the sound. perpendicular to away from towards at the same speed as
