John loads a collapsed inflatable boat into a two-wheeled "grocery type" hand cart and wheels it down to the lake. answer c. The cart will be easier to pull, in spite of the weight of the board, because now the angle of pull is much closer to the angle of movement. This explains finding a board 8 foot long to lengthen the underside of the cart.?
Yes, finding a board 8 feet long to lengthen the underside of the cart would help to make it easier to pull. By lengthening the underside of the cart, the angle of pull gets closer to the angle of movement, making it easier to maneuver the cart. This is because the longer board will distribute the weight of the collapsed inflatable boat more evenly, reducing the force required to pull it.
The statement given in answer c is stating that by attaching an 8-foot long board to the underside of the cart, the cart will be easier to pull. This is because the angle of pull will be closer to the angle of movement.
To understand why this is the case, let's break it down step-by-step:
1. John loads a collapsed inflatable boat into a two-wheeled "grocery type" hand cart. The boat is likely a bit heavy and may put some weight on the cart.
2. By attaching an 8-foot long board to the underside of the cart, it extends the length of the cart from front to back.
3. When John wheels the cart down to the lake, he needs to exert force to pull the cart forward. The angle at which he pulls the cart is important.
4. With a longer board attached to the cart, the boat's weight is distributed over a larger surface area. This extends the length of the cart's contact with the ground.
5. As a result, the angle of pull becomes much closer to the angle of movement. By having the angle of pull aligned with the direction of movement, it helps reduce the resistance and effort required to pull the cart.
6. Therefore, the statement is saying that attaching an 8-foot long board to the underside of the cart makes it easier to pull because the angle of pull is much closer to the angle of movement.
Overall, the longer board acts as a leverage point, distributing the weight of the boat more evenly and reducing the strain on John as he pulls the cart to the lake.
