1. The problem statement, all variables and given/known data A 100 kg man is walking on a tight cable. His safety harness has a strap that is attached to an overhead cable that will allow him to fall 1 meter before stopping him from falling any further. What is the force on the strap when it stops his fall at 1 meter. 2. Relevant equations v = at v^2 = 2ad Fd = KE = .5mv^2 a = 9.81 m/s^2 Weight = ma = m*9.81 3. The attempt at a solution v = sqrt (2*9.81*1) = 4.43 m/s KE = .5*100*(4.43)^2 = 981 J Fd = F*1 = KE = 981 J Force on the strap at the end of the 1 m fall is 981 N The man's weight is ma = 100*9.81 = 981 N Shouldn't the force on the strap after the one meter fall be greater than the man's weight?
