A child of mass M using a parachute reaches a terminal velocity V, with the air resistance directly proportional to the square of the child's velocity. If an adult of mass 3M uses the same parachute under exactly the same conditions, his terminal velocity will be closest to what?

  • physics 1 -

    weight=airfriction=constant(veloctity^2)

    so if weight in increases by 3, then velocity increases by sqrt3
