This is an impulse-momentum problem: you need to find the force required to change the ball's momentum to zero in a very short time. The key insight is that force and time are linked through the impulse-momentum theorem—a large change in momentum over a short interval demands a large force. Convert the mass to kilograms, find the momentum change, then use $F_{\text{avg}} = \frac{\Delta p}{\Delta t}$ to get your answer.
