A 25 kg kid is trying to jump into a small boat, which is stationary. The kid jumps with a velocity of 7.5 m/s to the west. However, instead of landing in the boat, he hits the side of the boat, and bounces
off with a velocity of 5.00 m/s to the east. If the boat was 150 kg, what would the boat's velocity be
afterwards?

Which statement best describes the superposition principle? a.) if two in-phase waves arrive simultaneously at a point, their amplitudes add up b.) if two out-of-phase waves arrive simultaneously at a point, their amplitudes add up c.) if two in-phase waves arrive at a point one after another, their amplitudes add up d.) if two out-of-phase waves arrive at a point one after another, their amplitudes adds up
