Homework Statement



Hi guys,

I just wanted to confirm I am doing this right. I have a graph of energy (Joules) vs. time (seconds). I need to get the force from this information. If I know the linear distance the object has traveled, can I use the work equation W= Force* Distance, and solve for force. Also I know this will give me average force, How do I find maximum force.

Thank you

W=FD

The Attempt at a Solution



Integrate the curve to find the total energy, then use the formula above to find the force since I already know the distance, however this will only give me average force.

Integrate the curve to find the total energy
If I understand your problem statement correctly, your graph shows the energy, not the power. There is no need to integrate it.

To find the force at a specific point, you need the velocity and the change in energy at that point. Can you calculate that? Can you relate those two to a force?
