Answer:
The coefficient is 0.90
Explanation:
Drawing a diagram makes thing easier, we will assume that the acceleration tends to zero because it start barely moving.

20/40=0.5 g/cm^3 becuase, mass/volume=density.
If you walk at a pace of 2 miles per hour for 5 hours, you should have walked 10 miles. You would be 2 miles away from your base camp.
E=mgh. 196=5kg*9.81m/s^2*h. So h=196/(5*9.81)=4m
