Physics Work: Solving a problem

The video tutorial explains how to calculate the work done by a tugboat pulling a ship with a constant force of 5000 Newtons over a distance of 3 kilometers. It emphasizes the importance of using consistent units, converting kilometers to meters, and applying the formula for work, which is force times distance. The final calculation results in 1.5 * 10^7 joules, with a brief discussion on expressing this in kilojoules.

What is the constant force exerted by the tugboat on the ship?

• 5000 Newtons

• 3000 Newtons

• 7000 Newtons

• 10000 Newtons

What is the formula used to calculate the work done by the tugboat?

• Force divided by distance

• Force plus distance

• Force times distance

• Force minus distance

Why is it important to ensure the force is in the direction of the distance when calculating work?

• To reduce the distance traveled

• To minimize the work done

• To ensure accurate calculation

• To increase the force applied

How many meters are equivalent to 3 kilometers?

• 3000 meters

• 300 meters

• 30000 meters

• 300000 meters

What is the work done by the tugboat expressed in kilojoules?

• 1.5 * 10^6 kilojoules

• 1.5 * 10^4 kilojoules

• 1.5 * 10^3 kilojoules

• 1.5 * 10^5 kilojoules
