According to newtons second law, force=mass*acceleration. If you could theoretically have a bowling ball fall at a completely constant speed thereby eliminating the acceleration would there be any force when it hit the ground?
Yes. Although I'd argue the ball wasn't really "falling" so much as it was traveling toward the ground.
Tie a rope to the bowling ball and lower it at a fixed speed. It will accelerate upwards when it strikes the ground (to a speed of 0, modulo any bouncing). The force of that acceleration will be transferred to the ground.
According to newtons second law, force = dp/dt, so force is the derivative of momentum wrt time, so f=ma if mass is constant
since there is a change in momentum when the ball hits the ground, there is a force that the ground applies to the ball and, 3rd law: the ball applies the same force to the ground
