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
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.
