Pluto was first observed in 1930, and its largest moon, charon, was discovered in 1978. a few years after charon’s discovery, astronomers were able to observe a series of eclipses as pluto and charon passed in front of one another. by studying how the brightness of pluto and charon changed as they eclipsed each other, astronomers were able to measure the masses and radii of both pluto and its moon. what did these measurements imply about the average densities of pluto and charon?

On a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 3.00 m/s.(a) what are the magnitude and direction of the velocity of the red glider after the collision? (b) is this collision elastic?
