Hey guys,(adsbygoogle = window.adsbygoogle || []).push({});

There is one more question I am having a problem with. Here it is:

You jump from the top of a boulder to the ground 2.07 m below. Calculate your deceleration on landing. Assume that in order to soften your landing, your legs will bend 0.510 m. Give your answer in units of g. Do not enter unit.

Here is what I have done so far. I have used the height to find out how fast you are when you reach the ground. I got v= 6.37 m/s. After that I know I have to use the distance of bending to determine over what distance you decelerate. I know I use the formula that relates the velocity to the distance. So I should use v^2 = v_o^2 - 2g(xf-xi). THat is the same formula I used to get the first answer. Maybe I am using the wrong formula. This problem and the one I posted before I have made like 10 attempts on LON CAPA and I don't know what to do anymore. Please help. Thank you,

jackie
