Okay, here's the deal:
Basketball player Darrell Griffith is on record as attaining a standing vertical jump of 1.2 m (4 ft). (This means that he moved upward by 1.2 m after his feet left the floor.) Griffith weighed 890 N (200 lb).
(B) If the time of the part of the jump before his feet left the floor was 0.300 s, what was the magnitude of his average acceleration while he was pushing against the floor?
16.2 m/s Correct
Use Newton's laws and the results of part (B) to calculate the average force he applied to the ground.
Okay, I tried various methods of solving this that have all failed (says it is wrong). I have two tries left - so any ideas?
Numbers I have tried:
1480
1470
291
1180
If I am close to within about 5 digits, it will tell me. So far, I haven't even had that luck.
Anyone?
