Understanding the Concept

Newton's Second Law of Motion states that the force acting on an object is equal to its mass times its acceleration:

* Force (F) = Mass (m) x Acceleration (a)

Calculation

1. Mass (m) = 80 kg

2. Acceleration (a) = 1.85 m/s²

3. Force (F) = (80 kg) * (1.85 m/s²) = 148 N

Answer: You need a force of 148 Newtons to accelerate the bicycle at 1.85 m/s².
