Calculate the minimum uncertainty in (a) the speed of a ball of mass 500 g that is known to be within 1.0 µm of a certain point on a bat, and (b) the position of a bullet of mass 5.0 g that is known to have a speed somewhere between 350.000 01 m s−1 and 350.000 00 m s−1 ?

1. explain how you calculate the net force in any direction on the box. 2. suppose an upward force of 15n is added to the box. what will be the net vertical force on the box? 3. what force could be applied to the box to make the net force in the horizontal direction zero? explain. 4. suppose a force of 25n to the right is added to the box. what will be the net force to the right?
