if a guy is in an elevator (55 kg for the person), and then he jumps straight uo- the scale will read 622 N. what is the acceleration of the guy at this instant?(adsbygoogle = window.adsbygoogle || []).push({});

how do you deal with this b/c i don't know how to do it unless he is still standing on the scale. i know there should be an acceleration. could someone help me start this question?

thanks, Lisa
