on a track with no friction, as the mass increased of a cart increased, the acceleration of a cart decreased. how would the acceleration of the carts be different if the track had friction like in real life?

The cart would eventually slow down and stop. now matter how slowly the cart is going, without friction it would never slow down and just keep rolling at the same speed forever as long as the mass was not increased.
