Question

a football player kicks a ball with a mass of 0.42 kg. the average acceleration of the football was 14.8 m/s². how much force did the kicker supply to the football? 6.22 m/s² 35.24 m/s² 35.24 n 6.22 n

Explanation:

Step1: Identify the formula

Newton's second law \(F = ma\), where \(F\) is force, \(m\) is mass, and \(a\) is acceleration.

Step2: Substitute the values

Given \(m = 0.42\space kg\) and \(a=14.8\space m/s^{2}\), then \(F=(0.42)(14.8)\).

Step3: Calculate the result

\(F = 0.42\times14.8=6.216\approx6.22\space N\)

Answer:

6.22 N
