This was the original question: A high jumper falling a 3.9 m/s, lands on a foam pit and comes to rest, compressing the pit a distance of 0.43 m. If the pit is able to exert an average fource of -1100 N on the high jumper in breaking the fall, what is the jumper's mass?(adsbygoogle = window.adsbygoogle || []).push({});

But Im not sure if Im supposed to multiply or divide 0.43m and 3.9 m/s

Ive narrowed the answer down to either 1845 kg or 121 kg.
