Your dynamics test is on Friday now!
Here’s a pdf of my solutions to the practice assignment. Please remember that your test will be very similar in form and content. Sorry for the errors.
Next up, here are the answers to the longer practice test:
- A. Friction to the left, normal force up, gravity down, applied force broken down into horizontal (right) and vertical (down) components. B. 6.6 m/s^2
- A. 6.7 N B. 23 N C. 26 N
- 3.3 m/s^2 to the right
- 2.2 m/s^2 to the left
- A. tension up, gravity down B. 149 N
- 7.4 m/s^2
Finally, Flipping Physics has a review video for Dynamics:
