Right. What standard equations might be relevant?

 

[Nick63]

Right. What standard equations might be relevant?

acceleration= all forces working on object/mass?

 

[haruspex]

acceleration= all forces working on object/mass?

Sort of. To be accurate, Acceleration = net force on object / mass.

 

[Nick63]

Sort of. To be accurate, Acceleration = net force on object / mass.

so the acceleration would be 2 m/s?

 

[haruspex]

so the acceleration would be 2 m/s?

m/s is a speed, not an acceleration.

 

[Nick63]

m/s is a speed, not an acceleration.

oh 2m/s^2?

 

[haruspex]

oh 2m/s^2?

Yes.

 

[Nick63]

Yes.

Thank you so much it helps a lot to be able to talk a problem out
