Formula for the maximum height:
h = v i² / 2 g
If the initial speed is tripled:
h 1 = ( 3 v i )² / 2 g
h 1 = 9 v i² / 2 g = 9 h
Answer:
A ) the maximum height increases by a factor of 9.
Lines of latitude (parallels) run east-west around the globe and are used to measure distances NORTH and SOUTH of the equator. Since the equator is 0 , the latitude of the north pole, 1/4 of the way around the globe going in a northerly direction, would be 90 N.
