Question

select the correct answer. according to newtons second law, how much force will be required to throw a plastic ball and an iron ball of the same size through the same distance? a. the iron ball will require lesser force than the plastic ball. b. the plastic ball will require lesser force than the iron ball. c. both the balls will require the same force. d. the plastic ball will require more force than the iron ball.

Explanation:

Newton's second law is \(F = ma\) (force equals mass times acceleration). Assuming the same acceleration (to throw through the same distance, if we consider the motion - related acceleration during the throw process, and same - sized balls imply similar volume, but iron has a higher density than plastic, so \(m_{iron}>m_{plastic}\)). Since \(F = ma\) and \(a\) is assumed to be the same (for the throw - related acceleration to achieve the same distance in a simple - model sense, neglecting air resistance etc. for the purpose of comparing forces based on mass), then \(F_{plastic}

Answer:

B. The plastic ball will require lesser force than the iron ball.
