3. In science, work is defined as using a force to move something a distance. The formula for work W (in joules) Is W = F•d, where F is the force (in newtons) and d is the distance (In meters). Part A: Explaln how to solve the formula for force. Part B: Chantelle pushes a box 4.5 meters, doling 144 joules of work. What force does she use to push the box? Part C: Chantelle then pushes the box 9 meters, twice as far as in Part A. She does the same amount of work as in Part A, 144 joules. What force does she use? Part D: In general, if the distance an object is moved is doubled, but the amount of work done does not change, how does the amount of force used change?
