Question

In an inertial frame of reference, a series of experiments is conducted. In each experiment, two or three forces are applied to an object. The magnitudes of these forces are given. No other forces are acting on the object. In which cases may the object possibly move at a constant velocity of 256m/vs?1. 2 N; 2 N2. 200 N; 200 N3. 200 N; 201 N4. 2 N; 2 N; 4 N5. 2 N; 2 N; 2 N6. 2 N; 2 N; 3 N7. 2 N; 2 N; 5 N8. 200 N; 200 N; 5 N

Answer 1

1, 2, 4, 5, 6, 8

Step-by-step explanation:

1. 2 N; 2 N

2. 200 N; 200 N

3. 200 N; 201 N

4. 2 N; 2 N; 4 N

5. 2 N; 2 N; 2 N

6. 2 N; 2 N; 3 N

7. 2 N; 2 N; 5 N

8. 200 N; 200 N; 5 N

The net force of the system should be 0 in order for the body to move at a constant velocity.

So, the options 1, 2, 4, 5, 6, 8 have net force equal to zero so they are possibly maintaining the speed of 256 m/s
