Question

5. A tugboat used 153,000 watts of power to pull a broken-down cargo

a. If it took 3,600 seconds to do this, how much work was done by the tugboat?

b. If the tugboat pulled the cargo ship with a force of 306,000 N, how far was it pulled?

Answer 1

the work done by the tugboat was 550,800,000 J and the distance that the cargo ship was pulled was 1,800 m

Step-by-step explanation:

To solve this problem, we need to use the following formulas:

Work done = Power x Time

Power = Force x Velocity

Work done = Force x Distance

a. To find the work done by the tugboat, we can use the first formula and plug in the given values:

Work done = Power x Time Work done = 153,000 W x 3,600 s Work done = 550,800,000 J

b. To find the distance that the cargo ship was pulled, we can use the third formula and rearrange it to solve for distance:

Work done = Force x Distance Distance = Work done / Force Distance = 550,800,000 J / 306,000 N Distance = 1,800 m
