One soccer player (m1 = 65kg) is traveling with a velocity of v1 = (4.5 j) m/s. this player collides with a second player who has a mass of m2 = 72 kg who is traveling with a velocity of v2 = (3.3 i - 2.2 j) m/s. the players tangle together when they collide (a totally inelastic collision). what is the speed of the combined mass just after the collision? give your answer in unit vector notation.

An asteroid is discovered in a nearly circular orbit around the sun, with an orbital radius that is 2.47 times earth's. what is the asteroid's orbital period, its "year," in terms of earth years?

The intensity of a polarized electromagnetic wave is 12 w/m^2. part a) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=0∘ with the plane of polarization? part b) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=30∘ with the plane of polarization? part c) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=45∘ with the plane of polarization? part d) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=60∘ with the plane of polarization? part e) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=90∘ with the plane of polarization?
