Mr. Baldermann is at the grocery store to buy some chocolate milk. Unfortunately, the people at the store didn't stock the product well and everything is still in boxes. In order to to get to the box containing the chocolate milk, he has to move 3 boxes out of the way. To move Box A, Mr. Baldermann uses 5N of force and it moves 3m. Box B requires 8N of force and it moves 16m. Box C needs 10N of force to move it 2m. Calculate how much work is done moving each box and the total work done moving all 3. Your answer should include all of this: Box A work: Box B work: Box C work: Total work:. Remember to show your work.
What is Box A: 15j Box B: 128j Box C: 20j Total: 163j

Explain Newton's 3 laws of motion and give an example of each of how each one works.
What is Law 1: an object at rest remains at rest and an object in motion remains in motion unless acted on by an unbalanced force Law 2: The acceleration of an object depends on the mass of the object and the size of the net force applied Law 3: When a force is applied to an object, the object exerts an equal force in the opposite direction
