Using a rope that will snap if the tension in it exceeds 387 N,you need to lower a bundle of old roofing material weighing 449 Nfrom a point 6.1 m above the ground. Obviously if you hang thebundle on the rope, it will snap. So, you allow the bundle toaccelerate downward. (a) What magnitude of the bundle'sacceleration will put the rope on the verge of snapping?
T-mg = -ma
Why are most of the solutions out there is just T-mg = ma?
Since acceleration down, is opposite direction of T, why is theequation to solve this is not T-mg = - ma ?
