Homework Statement
a) Starting From Newtons second law, find the location of the rock as a function of time in horizontal and vertical Cartesian coordinates
b) If r(t) is the distance the rock is from its starting point, what is the maximum value of θ for which r will continually increase as the rock flies through the air?
Homework Equations
F=ma
The Attempt at a Solution
a) So as the question asks, I start with Newtons second law, that being, f=ma so Fnet=dp/dt (where p=mv), Knowing this am I just to integrate m*dv/dt in vector form?
So I would get something like r(t) = v(t)-1/2a(t)^2 i + v(t)-1/2a(t)^2 j?b) haven't got that far
