Q. A 107N grocery cart is pushed 14.00 m along an aisle by a shopper who exerts a constant horizontal force of 40.00 N. If all frictional forces are ignored and the cart starts from rest, what is the grocery cart's final speed?

Q. An airtight box has a removable lid of area 1.10 multiplied by 10-2m2 and negligible weight. The box is taken up a mountain where the air pressure outside the box is 0.80 multiplied by 105 Pa. The inside of the box is completely evacuated. What is the magnitude of the force required to pull the lid off the box?
