Homework Statement
Ok, so I'm having a lot of trouble finding time when it is not given in a projectile motion problem. Here's what I have set up:X
A=O
Vi=100.0
VF=100.0
D=?
T=?
Y
A=-9.8
Vi=O
Vf=?
D=8848m
T=?
Homework Equations
Distance(d=1/2at2=vit)
The Attempt at a Solution
Ok, here's where my problem is, I can never get the time right. I have failed 2 tests and numerous homework assigments because something is wrong. Here's my attempt at it:
8848=1/2(-9.8)t2
I divide both sides by 8848 then square root it.
I ALWAYS get the wrong time and in turn that gives me the wrong distance and in turn I fail the test.
