Using the same cord, what would be the maximum upward acceleration you could impart to a suspended 5.0-kg mass?
Refer to the following information for the next two questions.
A 50-kg woman stands on a spring scale inside an elevator.
If the scale reads the normal force supplied by the floor of the elevator on the woman, what would it read when the elevator is accelerating downward at 3.0 m/s
^{2}
?
340 N
490 N
640 N
What would the spring scale read as the elevator approaches the first floor if it slows to a stop at 3 m/sec
^{2}
?
Refer to the following information for the next two questions.
A 60-kg prisoner wishes to escape from a third-story window by going down a rope made of bedsheets tied together. Unfortunately, the rope can only sustain a maximum tension of 500 N.
How fast must the prisoner accelerate down the rope if it is not to break?
1.47 m/sec
^{2}
8.33 m/sec
^{2}
11.3 m/sec
^{2}
18.1 m/sec
^{2}
Why should he have not slid down the rope at a constant velocity?
