Homework Statement
Looking for F for 200 km/hr
Homework Equations
F=ma
The Attempt at a Solution
Fcv^2 = ma
F= ma +cv^2
v=200 km/hr
F= ma +c(200 km/hr)^2
so now I need to find a, from previous work I found that
t= (m/c)*(1/2 vter)*(ln[ (vter +v)/(vterv)])
next I would solve for v and take the derivate to get a.
but I know that
v^2 =v0^2+2a( x x0)
where
a= v^2v0^2 / 2(xx0)
I know that v=2000 km/ hr
v0=0 since it was at rest
x= final distance
x0=0 since it starts at the origin
