Question

how much force is required (in newtons) to accelerate a 10-kg bicycle, along with its 60-kg rider, at 2.5 m/s²

Answer 1

Force = mass X acceleration,

The Force in Newtons is defined as kg*m/sec²

mass is kg

acceleration is m/sec²

^

First, get the total mass, then multiply by the acceleration
