Jason, some of the quantities are not clear. In any event, you will have to convert all units to kilograms, meters, and seconds.

m=5.5oz X .283 kg/oz=

It isn't clear what the 15 ft represents, is it the distant the "impact" force acts through?

d= 15 ft X .305 m/ft=

Is the "speed" 75km supposed to be km/hr? if so V = 75km/hr x 1000m/km x 1/3600 hr/s=

IS this V the final speed starting from 0 speed?

If the "impact" is the force F that accelerates the ball through 15 ft starting from rest then

F=m**a **and** "a" **can be determined by solving V^{2}_{f} = V_{i}^{2} - 2**a**d for** a**
