In an inelastic collision, a steel ball of mass 200 g was hit hard into a large ball of dough of mass 700 g. The velocity of the steel ball was 25m/s. After the collision, the steel ball was stuck in the dough, and this combined system rolled for some time.

What was the velocity of the system of the steel ball and dough after the collision?

A) 5.6 m/s

B) 7.5 m/s

C) 8.8 m/s

D) 11.1 m/s
