Raul kicked a soccer ball. The ball approached Raul's foot with a momentum of magnitude pi = 11.2 kg m/s. The ball left his foot with a momentum of magnitude pf = 14.2 kg m/s. The orientation of the initial and final momentum vectors is shown in the diagram above, with the smallest angle between the incoming and outgoing vectors being θ = 58 degrees, as shown. The ball was in contact with Raul's foot for an amount of time equal to 7.3 ms (that says milliseconds). Assuming all other forces are negligible by comparison, calculate the magnitude of the average force (in newtons) that Raul exerted on the ball during those 7.3 milliseconds.
