Physics Work: Solving another problem

The video tutorial explains how to calculate the work done when pushing a shopping cart at an angle. It covers the concepts of force, angle, and distance, and demonstrates how to use the formula for work, which involves the cosine of the angle to find the component of force in the direction of motion. The tutorial also includes a conversion of the result from joules to kilojoules, providing a practical example of unit conversion.

What is the angle at which the force is applied to the shopping cart?

• 15 degrees

• 25 degrees

• 35 degrees

• 45 degrees

Which formula is used to calculate the work done when the force is applied at an angle?

• F * D

• F * sin(Theta) * D

• F * cos(Theta) * D

• F * tan(Theta) * D

What is the component of the force that contributes to the work done in the direction of motion?

• The horizontal component

• The vertical component

• The entire force

• The perpendicular component

What is the work done on the shopping cart in joules?

• 1450 joules

• 1600 joules

• 1350 joules

• 1586 joules

How do you convert 1586 joules to kilojoules?

• Divide by 1000

• Multiply by 1000

• Add 1000

• Subtract 1000
