High Resolution Clear Image Of A Fast Moving Object

I am looking for the right camera to produce a high resolution clip of an object moving 8mph, where the camera is located 5 feet from the moving object. We need to be able to play back the clip, hit pause, and have a perfect frame, no motion blur every time.

I am not sure how much the camera matters as much as the shutter speed does here.

8mph = ~12 feet a second

Not clear what your FoV is but let's say it is 6 feet wide, so in 0.5 seconds, the object will pass through the complete FoV. If you choose something like 1/500s shutter speed, I think you will be in good shape to get no motion blur but ultimately you can go into the camera's settings and just try a few shutter speeds to find the right balance.
