what exactly is a kN? to find the tension of part a what equation would I use? for b) I need to make a=-1.22m/s^2 but I am not sure what the equation I would use be.I should be getting 31.3 kN for a) and 24.3kN for part b but I can't figure out my problem.

Tension= mg + ma when going up.

Tension = mg - ma when going down. Think that out.

kN is kiloNewtons
