Question

Tyler asks to go get water, taking the hall pass. Rather than coming right back, she stands outside every teacher’s classroom, waving hi with the hall pass in her hand. She traveled 20 meters using a force of 0.5N to carry the hall pass. What is the amount of work Tyler did, rather than being in science?

Answer: ?

2. Suppose Julieta M. was putting on lip gloss and Ciara used 3N to take the lip gloss. She then hid it across the room for a total of 18 Joules of work. How many meters did Ciara walk across the room?

Answer: ?


3. Imagine that Yamielth and Cianna are asked to bring Mr. Williams a few copies of behavior charts for 6-2, taking the office pass. They traveled 4 meters, however, Yamileth completed 28 Joules of work while Cianna completed 36 Joules of work. Calculate the amount of force each girl used to get Mr. Williams the copies and which student used greater force.

Answer: ?

Answer 1

Step-by-step explanation:

1) The amount of work done by Tyler is equal to the force applied multiplied by the distance over which the force is applied. In this case, the force applied is 0.5 N and the distance is 20 meters. So, the work done is 0.5 N x 20 meters = 10 Joules

2) The work done is equal to the force applied multiplied by the distance over which the force is applied. In this case, the work done is 18 Joules and the force applied is 3 N. To find the distance, we can divide the work by the force: 18 Joules / 3 N = 6 meters

3) To find the force applied by each girl, we can use the formula work = force x distance.

Yamileth: 28 Joules = force x 4 meters => force = 28 Joules / 4 meters = 7 N

Cianna: 36 Joules = force x 4 meters => force = 36 Joules / 4 meters = 9 N

Yamileth used a force of 7 N to get Mr. Williams the copies and Cianna used a force of 9 N. Therefore, Cianna used greater force than Yamileth.
