A bullet (mass of 20 kg) is fired at a person wearing a bulletproof vest at 1500 m/s. The person is knocked back at 20 m/s but survives. The bullet just stops.

a. What are the magnitude and direction of the impulse imparted by the person on the bullet?

b. Calculate the force exerted by the person on the bullet (ignore gravity).
