Hi guys

I’ve a problem calculating the vertical jump from ground reaction force. We tested a person with a force plate, and we got this curve as a result:

**2. Relevant equations**

These are the equations, sorry for the danish language, but just look at the equations and not the text.

**3. The attempt at a solution**

fg is 9.82, but maybe it should be the persons weight in newton?

deltat= 0.04, but maybe it should be (2.44-1.34) because that is the time for the entire jump?

Either way, i don’t get a useful result.

Thanks for looking at it, feel free to ask if you need additional info đź™‚
