14 kg*/s=(9 kg) (5 m/s)s

14 kilogram per second equals to left paren 9 kilogram right paren left paren 5 metre per second

45 kg*m/s=(9 kg) (5 m/s)

45 kilogram asteric metre per second equals left paren 9 kilogram right paren left paren 5 metre per second right paren

4 kg*m/s=(9 kg) (5 m/s)

4 kilogram asteric metre per second equals left paren 9 kilogram right paren 5 metre per second left paren

45 N=(9 kg) (5 m/s)

Answer 1

Correct answer: "45 kg*m/s = (9 kg)(5 m/s)".

Explanation: p = mv = 9 kg × 5 m/s = 45 kg·m/s. The other choices have wrong numbers or wrong units (e.g., N is a unit of force, not momentum).
