inflatable boat handles

Can you help me with science please?

John loads a collapsed inflatable boat in a two-wheel "type grocery store" and the wheel barrow down to the lake. (A) Although the cart on wheels is tipped at an angle of approximately 45 degrees (in other words, about halfway between horizontal and vertical.) Finds John This exhausting because they attract quite difficult to move the cart. After hearing a suggestion of friends, he tries an experiment. (B) He used an eigh-meter board extending from the underside of the car (the side of the cart that faces down, while the cart is dumped and pulled along). The end of the board serves as a new extended handle of his cart. Now when he goes to his "pull more" car, he was pulling the car on a 20-degree angle (much closer than before). Based on what you read on the direction of the force and motion, what happens? A) the cart will be harder now to make as the bottom 2 of the ground. B) the cart will b difficult to make because of the extra weight c) It will easily d) there is no change.

It will certainly be easier to lift and thus less tiring and because you said the more he takes it to the extra weight No problem, so I'm going to answer C). Coming back home go up, so the extra weight of the large grip will cause some extra energy requirements, but it still can be offset by the extra comfort.
