1. Homework Statement
I'm doing lab, and to start we have to find ΔX of a projectile launched an angle. The first step for us is to find time, and to make it easier our teacher recommended us to first set the angle to zero, and find time like that.
I don't have enough X information to find time yet, so I have to use the Y components I think
X
ΔX= .153 M
Φ = 0°
Y
AY = 9.8m/s2
ΔY = -.96 M.
Φ = 0°
Viy = 0 ?
I'm supposed to take the equation ΔY = Viyt + 1/2ayt2 and make it into quadratic formula. For some reason t = √2ΔY/AY won't work and we're supposed to use quadratic formula
[/B]
Since I'm launching the projectile from 0°, I thought the Viy would equal 0. However, when I try to plug that into the quadratic formula, there's a 0 for one of the variables and it doesn't work.
I'm getting -4.9t2 + 0 + .96 = 0; I think I'm doing something wrong in the middle but I'm not sure what to fix.
