Homework Statement
The brave fish launches himself from a 6 cm cannon straight up in the air. When he leaves the cannon he is traveling at 6.5 m/s. assume constant acc while in the cannon.
How long was the fish in the cannon?
Homework Equations
v^2=Vo^2+2ax
X= Xo + Vot + 1/2at^2
X=height
Xo=initial height
Vo=initial velocity
t=time
The Attempt at a Solution
6.5^2=0^2+2a(.06)
a=352.08m/s^2
352.08=u-9.8 (u=up acc)
u=361.88m/s^2
x=1/2at^2
.06=1/2(361.88)t^2
t=.02sec
