The amplitude of wave is___ A) the distance the wave moves in one second

B) the distance between one crest and the next crest

C) half the distance from a crest to a trough

D) the distance equal to one wavelength

To practice problem-solving strategy 10.1 for energy conservation problems. a sled is being held at rest on a slope that makes an angle θ with the horizontal. after the sled is released, it slides a distance d1 down the slope and then covers the distance d2 along the horizontal terrain before stopping. find the coefficient of kinetic friction μk between the sled and the ground, assuming that it is constant throughout the trip.
