You slide a W= 600 N table across the horizontal kitchen floor by pulling with a force of 400 N. If the table moves at a constant speed, the friction force with the floor must be: more than 400 N 400 N 600 N O more than 600 NA golf ball is hit into the air, but not directly upwards, and encounters no significant air resistance. Which statement accurately describes its motion while it is in the air O on the way up it is accelerating upward and on the way down it is accelerating downward O on the way up both the horizontal and vertical components of velocity are decreasing O the vertical acceleration is constant and always points downward O the horizontal velocity does not change once it is in the air, but the vertical velocity does change O C and D are both true
