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?
But I am not sure if I...
Ok I am back.
Now I've got it down to two answers but I am not sure if I am supposed to multiply or divide at a certain point.
Is it - 0.43 * 3.9 = 1.677 * 1100 = 1845
or is it - 0.43/3.9m/s = 0.1102 * 1100 = 121
Or am I completely off?
Please help..
I have tried many times to figure out the formula to solve this problem. I have drawn diagrams & searched through my book numerous times. If I just had the formula to solve it, I would be fine. I don't have a scanner so I can't show you all the diagrams & whatnot but here is the problem.
