You have been accepted into a boat building competition. You get to pick between two boat plans. Boat A’s plans has the dimensions of 45m wide and 126m long and exerts 2300Pa of pressure. Boat B’s plans has the dimensions of 6m wide and 115m long and exerts 2700Pa of pressure. In order for the boat to float, the force applied to the water must not exceed 2.0 X 10 6 N. Would you pick Plan A or Plan B?

Drag each tile to the correct box. tiles bra i sequence

As you are trying to move a heavy box of mass m, you realize that it is too heavy for you to lift by yourself. there is no one around to , so you attach an ideal pulley to the box and a massless rope to the ceiling, which you wrap around the pulley. you pull up on the rope to lift the box. use g for the magnitude of the acceleration due to gravity and neglect friction forces. once you have pulled hard enough to start the box moving upward, what is the magnitude f of the upward force you must apply to the rope to start raising the box with constant velocity? express the magnitude of the force in terms of m, the mass of the box.
