Question

A tool bag is going to be pulled straight up from the ground to the top of the building by a long cable . Starting from rest, the bag accelerates upward at 2.3 m/s^2.

a)calculate how high it rises in 7.0s

b) At this instant, the tension in the cable is reduced and the bag begins slowing down at a rate of 4.1m/s^2 and stops just as it reaches the top of the building. How tall is the building and draw a Free body diagram of the bag whiles it's in the air during the interval you choose.

c) calculate the magnitude of the tension Force FT the cable exerts on the bag during the interval you chose. The bags's mass is 29kg.
