Two ice skaters not paying attention collide in a completely inelastic collision. Prior to the collision, first skater, with a mass of 60 kilogram, has a velocity of 5.0 km/h eastward, and moves at a right angle to second skater, who has a mass of 75 kilogram and a velocity of 7.5 km/h southward. Obtain the velocity of the skaters after collision?
