newtonian mechanics - Why doesn't static friction decelerate a rolling body?


I know that static friction isn't the cause of deceleration of a rolling body. But if static friction is the only force in the horizontal direction, then shouldn't there be some acceleration produced in this direction? The body should decelerate or accelerate. So how come in this case, a force does not produce acceleration?


Please help! I have been pondering on this question for a long time.
