Explain how two rolling bowling balls of different masses can have the same momentum

Wrong two where not rolling at same time and speed

Knowing that the momentum(p) of an object is directly (when one number goes up the other will too) related to both the mass and velocity of an object or p=mv, two rolling bowling balls of different masses can have the same momentum because the one with the lower mass, has a higher velocity. The higher velocity of an object would make up for the lower mass and vice versa.

at positions a, g kinetic energy is maximum.

at position d, potential energy is maximum.

it has to be b, about 97 percent.
