Question

A 30.0 kg bike accelerates at 7.0 m/s2. How much force is applied to the bike?

Answer 1

According to Newton's Second Law of Motion, the net force F that acts on an object with mass m that accelerates at a rate a is:

`F=ma`

Substitute m=30.0kg and a=7.0m/s^2 to find the net force on the bike:

Then, the net force applied to the bike, is 210 N.
