To calculate the force with which the person is pedaling, we need to use Newton's second law of motion, which states that the net force acting on an object is equal to the mass of the object times its acceleration. In this case, the net force is the force applied by the person pedaling the bike. Therefore, we have:
Net force = mass x acceleration
Substituting the given values, we get:
Net force = 20 kg x 10 m/s^2
Net force = 200 N
Therefore, the force with which the person is pedaling the bike is 200 N.
