You are applying force to an empty grocery cart and accelerating it at 10 m/s2. As you add groceries to the cart, its mass increases. A) Based on Newton’s 2nd Law of Motion, what do you need to do to the net force you are applying to the cart in order to maintain an acceleration of 10 m/s/s. B) Explain why you need to do that, using Newton’s 2nd Law.

Increase applied Force

Explanation:

In order to maintain the same acceleration, the net force should be increased with the increase in mass of the cart by adding the Groceries.From Newton's Second law of motion , we obtain expression as: F=Ma; where F is net force, M is mass and a is acceleration.from the above expresssion, we can observe that force is proportional to the mass; hence we need to increase force with increase in mass.
