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?
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)
