Asked by Layla
A rifle is aimed horizontally at a target 100 ft away. The bullet hits the target .78in below the aiming point.
a) What is the bullet's time of flight?
b)What is its muzzle velocity?
The answers should be
a) 63 m/s
b) 1.6 X 10 exponent 3 ft/s
I don't know how to get to these answers-how to solve it.

Y=0.75inch=0.75/12 ft=1/16 ft
x=100ft
t=? Vo=? g=32ft/s^2
1/16=0 + 1/2gt^2
t^2=2*1/16*32 =(1/16*16)^1/2
=6.25*10^-2sec
x=Vox*t=Vox=x/t=1600ft/s
x=100ft
t=? Vo=? g=32ft/s^2
1/16=0 + 1/2gt^2
t^2=2*1/16*32 =(1/16*16)^1/2
=6.25*10^-2sec
x=Vox*t=Vox=x/t=1600ft/s
