Would the actual velocity be larger/smaller?

I was wondering if the bearing is too tight, how would the initial of the ball be affected during a momentum collision? Would the actual velocity be larger/smaller?

If by 'the bearing is too tight' you mean the wheels slip and don't rotate then the velocity will be reduced because the cart will lose energy to friction as the wheels skid.

The actual velocity of the ball would depend on various factors such as the mass and velocity of the object it is colliding with, the elasticity of the materials involved, and the angle and force of the collision. The tightness of the bearing would not directly affect the initial velocity of the ball, but it could indirectly impact the outcome of the collision.

If the bearing is too tight, it may create more friction and resistance for the ball to move, which could potentially decrease its initial velocity. However, if the bearing is too loose, it could cause the ball to lose momentum and decrease its velocity as well. Ultimately, the actual velocity of the ball would depend on the specific circumstances of the collision and cannot be determined solely based on the tightness of the bearing. I would suggest conducting experiments to measure the effects of bearing tightness on momentum collisions to better understand its impact on velocity.
