If a 180 pound body is dropped from an airplane 5 miles (26400 ft.) up:
a/ how long would it take for the body to
reach the ground?
b/ what would be the maximum speed the
body would attain in miles per hour?
Close approximations are all that are required here. Thanks.
a. See previous post: Thu, 11-19-15, 9:46 PM.
b. V^2 = Vo^2 + 2g*h.
Vo = 0.
g = 9.8 m/s^2.
