Amy has a mass of 30 kg and she is riding a skateboard traveling 5 m/s what is her momentum a. 5 kg* m/s b. 6 kg* m/s c. 30 kg* m/s d. 150 kg* m/s

Momentum = mass  ×  velocity

Based on the question, mass = 30 kg; velocity = 5 m/s

⇒  Momentum = 30 kg × 5 m/s
                          =  150 kg · m/s  [OPTION D]

20 percentage, you can also do it on a calculator.
