Question

A soccer player kicks a soccer ball of mass 0.50 kg that is initially at rest. The player's foot is in contact with the ball for 1.8 10-3 s. The force of the kick is given by the following formula for 0 t 1.8 10-3 s, where t is in seconds. F(t) = [(7.2 106)t - (2.2 109)t2] N (a) Find the magnitude of the impulse imparted to the ball. Incorrect: Your answer is incorrect. Ns (b) Find the magnitude of the average force exerted by the player's foot on the ball during the period of contact. N (c) Find the magnitude of the maximum force exerted by the player's foot on the ball during the period of contact. N (d) Find the magnitude of the ball's velocity immediately after it loses contact with the player's foot. m/s
