This is a fixed question bank. Later sets may repeat these questions
Each row is a separate run on a level track. The horizontal forces and mass stay constant during each run. Gravity and support balance; ignore horizontal resistance
Both 3 kg carts start moving right at 1 m/s. Only the listed cable pulls act horizontally, for the same 2 s
| Run | Left (N) | Right (N) |
|---|---|---|
| A | 1 | 4 |
| B | 3 | 6 |
