A 75 kg petty third wants to escape from a third story jail window. Unfortunately, a makeshift rope of sheets tied together can support a mass of only 50 kg. What is the minimal acceleration with which the thief must lower himself so he may use the "rope" without breaking it? the variables i got were: m=75 kg a= -9.80m/s^2 v1=0 i then tried to use the formula for the thief, f=ma, isolated for a, a=f/m and substitued it into the rops max acceraltion limit, which formula is f=ma i then got f(thief)/m(thief)= f(rope)/m, and i dont really know where to continue from there, because the thief must accelerate at a slower rate than what gravity plans for him, and must be a lower acceleration than 50 kg would normally fall right? please help!
