v=0 at max height t=15sec g=10m/s2
v=u+gt
-u=-gt u=10x15= 150m/s
v^2-u^2=2gh
150x150=2x10x h
h=150x150/20
h=1125m
v=u+gt
-u=-gt u=10x15= 150m/s
v^2-u^2=2gh
150x150=2x10x h
h=150x150/20
h=1125m
G??? What's g?
its acceleration due to gravity and its value is 9.8 or 10 m/s^2
G is universal gravitation constant
