Question

Naoki's bicycle has a mass of 12 kg. If Naoki sits on her bicycle and starts pedaling with a force of 184.8 N, causing an acceleration of 2.8 m/s2, what is Naoki's mass?

Answer 1

Answer:

54 kg

Explanation:

Use Newton's second law.

F = ma

184.8 N = (m + 12 kg) (2.8 m/s²)

66 kg = m + 12 kg

m = 54 kg
