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 N
from a point 6.10 m above the ground. (a) What
magnitude of the bundle’s acceleration will put the rope on the
verge of snapping? (b) At that acceleration, with
what speed would the bundle hit the ground?
How many forces act on the bundle?
