How much force is required in Newtons) to accelerate a 12-kg bicycle, along
with its 50-kg rider, at 2 m/s2?
Give your answer as a number.
Answer here

Force, F = 124 N

Explanation:

We have,

Mass of bicycle is 12 kg and mass of rider is 50 kg

Total mass of the system is 12 kg + 50 kg = 62 kg

Acceleration of the system is 2 m/s²

It is required to find the force required to accelerate the system. The force acting on an object is given by :

So, the force of 124 N is acting on the system.  

a.) travels faster in solids because the particles are closer together.
