A force of 100N was used to kick a football of mass 0.8kg. Find the velocity with which the ball moves if it takes 0.8s to be kicked

Question 1 Report

32ms−1

50ms−1

64ms−1

100ms−1

100 m s^{- 1}

Answer Details

The velocity with which the football moves can be found using the formula: v = (F*t) / m where F is the force applied, t is the time for which the force is applied, and m is the mass of the football. Substituting the given values, we get: v = (100 * 0.8) / 0.8 = 100 m/s Therefore, the velocity with which the ball moves is 100 m/s. Note that the answer is not one of the given options. The correct answer is 100 m/s, which is a very high velocity for a football and is unlikely to be achieved in practice.
