Concept explainers
Each diagram shows a ball traveling from left to right. The position of the ball each second is indicated by the second. Rank the net forces from greatest to least required to produce the motion indicated in each diagram. Right is positive and left is negative.
The ranking of net forces from greatest to least.
Answer to Problem 21A
Explanation of Solution
Introduction:
According to Newton’s second law of motion, force is the product of acceleration and mass. Mathematically,
Description:
The displacement of the position of the ball to the right will be taken as positive and to the right it will be taken as negative. Hence, according to the figure, in case of D, the balls are having the greater area of contact between them.
Conclusion:
Hence, the ranking is:
