Answer:
The work done to get you safely away from the test is  2.47 X 10⁴ J.
Explanation:
Given;
length of the rope, L = 70 ft
mass per unit length of the rope, μ = 2 lb/ft
your mass, W = 120 lbs
mass of the 70 ft rope  = 2 lb/ft x 70 ft
                                          = 140 lbs.
Total mass to be pulled to the helicopter, M = 120 lbs  + 140 lbs  
                                                                        = 260 lbs
The work done is calculated from work-energy theorem as follows;
W = Mgh
where;
g is acceleration due gravity = 32.17 ft/s²
h is height the total mass is raised = length of the rope = 70 ft
W = 260 Lb x 32.17 ft/s²  x 70 ft
W = 585494 lb.ft²/s² 
1 lb.ft²/s² = 0.0421 J
W = 585494 lb.ft²/s²  = 2.47 X 10⁴ J.
Therefore, the work done to get you safely away from the test is  2.47 X 10⁴ J.

The layout of the stars in the sky is determined by the date, time of night, and your location (mainly latitude). So to pick the best star chart, you should go with the one that's closest to the present date and your location, then make allowance for what time it is. Everything in the sky moves about a degree every 4 minutes.
