Question

A ball with a mass of 1 kilogram is moving in a straight line at the same speed as a ball with a of 10 kilograms. both balls are brought to rest in 4.0 seconds. which of the following is true of the force required to stop the balls?

A. it takes less force to stop the 1 kilogram ball because it has less inertia.
B. it takes more force to stop the 1 kilogram ball because it has more inertia.
C. it takes the same force to stop both balls because they’re moving the same speed.
D. it takes less to stop the 10 kilogram ball because it has less inertia."

Answer 1

It takes less force to stop the 1-kilogram ball because it has less inertia compared to the 10-kilogram ball, in accordance with Newton's First Law of Motion.

Step-by-step explanation:

The question pertains to the force required to stop two balls of different masses moving at the same speed. Using Newton's First Law of Motion, we understand that inertia is directly related to mass. Therefore, it would take more force to stop the ball with a mass of 10 kilograms than it would to stop the ball with a mass of 1 kilogram because the 10-kilogram ball has more inertia. Inertia is the property of a body to remain at rest or to maintain its state of motion unless acted upon by a force. The correct answer to the question is that it takes less force to stop the 1-kilogram ball because it has less inertia (Option A).
