Homework Statement
A point mass m is exposed to a time dependent force F(t). Determine the position r(t) of the point mass for the initial conditions r(0) = [itex]r_{0}[/itex]and v(0) = [itex]v_{0}[/itex]
Homework Equations
The Attempt at a Solution
[itex]\sum[/itex]F= ma
[itex]F_{z}[/itex](t) - mg = ma
a = 1/m [itex]F_{z}[/itex](t) - g
v = 1/m [itex]\int[/itex][itex]F_{z}[/itex](t) dt - [itex]\int[/itex]g dt
but how do I start to int F(t) without knowing the equation for F itself?
