It seems as though you might have missed part of the problem statement.
Do you have to find the height of the rock 5 seconds after it is dropped from the North Rim at a height of 5700 feet? Using the given function:
h%28t%29+=+-16t%5E2%2B5700 Substitute t = 5 and solve for h.
h%285%29+=+-16%285%5E2%29%2B5700
h%285%29+=+-400%2B5700
h%285%29+=+5300feet.
The height of the rock would be 5300 feet five seconds after it was dropped from a height of 5700 feet.
