45 N=(9 kg) (5 m/s)
45 newton equals to left paren 9 kilogram right paren left paren 5 metre per second

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 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

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

Answer 1

The correct choice is:

45 kg·m/s = (9 kg)(5 m/s)

Because momentum p = m v = 9 kg × 5 m/s = 45 kg·m/s. (Newton is a unit of force, not momentum, and the other options have wrong units or numbers.)
