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.
