vf^2 = vi^2 - 2as
0 = (20)^2 - 2( 9.81)(s)
s= 20.3874 m.
If air resistance consumers 10% of the initial energy of the jet
s = [20.3874] - [20.3874*(10%)]
s = 18.3487 m.Ans. [A]
0 = (20)^2 - 2( 9.81)(s)
s= 20.3874 m.
If air resistance consumers 10% of the initial energy of the jet
s = [20.3874] - [20.3874*(10%)]
s = 18.3487 m.Ans. [A]
