A Princeton prof. (mass = 67.0 kg), surprised by the large stopping force he calculates for jumping flat footed from a height of 0.11 m, decides to try the experiment. Calculate he deceleration (in g's) if he stops in a distance of 0.30 cm. (Do not try this. You could easily break an ankle!)
Potential energy mgh
work stopping: force*distance
set them equal.
yeah you wanna do that and tell me what you get or just tell me what you used for the masses because i keep getting wrong.
i've gotten 41.57 41.92 and 5.68 when i only used the mass of the bullet
mass of the bullet? come back to planet Earth.
put height and distance in meters.
ha wrong question sorry.
