Question

Using the force diagram and net force, calculate the acceleration of the 2 kg object.


4.0 m/s2

16.0 m/s2

1.8 m/s2

8.0 m/s2

Answer 1

I don’t have the force diagram, so I can’t pick the right numeric answer yet. Tell me the forces and their directions (or attach the diagram) and I’ll compute the net force and acceleration.

Method:
- Sum the vectors to get F_net (in N).
- a = F_net / m. Here m = 2 kg, so a = F_net / 2.

For reference, the four choices correspond to these net forces:
- 4.0 m/s² → F_net = 8 N
- 16.0 m/s² → F_net = 32 N
- 1.8 m/s² → F_net = 3.6 N
- 8.0 m/s² → F_net = 16 N

If you tell me which forces act (magnitudes and directions), I’ll pick and show the work.
