Question

What is the magnitude of the cart’s acceleration? Use the information below and your knowledge of science to answer the two questions that follow. A constant eastward horizontal force of 70 newtons is applied to a 20 kilogram cart moving toward the east on a level floor. The frictional force on the cart has a magnitude of 10 newtons. 4. Which of the following correctly freebody diagrams correctly represents the forces acting on the cart?

Answer 1

The correct free body diagram for the forces acting on the cart would include:

- A vector arrow pointing towards the right representing the applied force (70 N)
- A vector arrow pointing towards the left representing the frictional force (10 N)
- A vector arrow pointing downwards representing the weight of the cart (which can be calculated as mass times gravitational acceleration, or 20 kg x 9.8 m/s^2)
