A boy kicks a football with a force of 20 N, the time the force acts for is 0.3 s. Calculate the impulse on the ball. 66 N.s 6N.s 1 N.S None of these

The correct answer is 6 N.s.<br /><br />Impulse is defined as the change in momentum of an object when a force acts on it for a certain period of time. It can be calculated using the formula:<br /><br />Impulse = Force x Time<br /><br />In this case, the force applied on the football is 20 N and the time for which the force acts is 0.3 s. Substituting these values into the formula, we get:<br /><br />Impulse = 20 N x 0.3 s = 6 N.s<br /><br />Therefore, the impulse on the ball is 6 N.s.
