a boy of mass 60 kg is holding a vertical rope the rope can break when mass of 75 kg is suspended from it the maximum acceleration with which the boy can climb the rope without breaking it is |

Answer» Answer: 0.25 m/s^2. Explanation: The tension in the STRING or the breaking force of the string will be 75g N. So, on making a free body DIAGRAM, the boy who is having a weight of 60G will pull the string down with an acceleration a. So, Tension or breaking STRESS =m(g+a) or 75g=60g+60a which on solving we will get that a=15/60 or 1/4 = 0.25 m/s^2. So, the MAXIMUM acceleration with which the boy can climb the rope is 0.25 m/s^2. |
