how do you make an equation for a falling object that is being thrown upwards?

Question

anonymous · Answer

make $v_0$ your initial velocity positive

anonymous · Answer

If this is a calculus course, the best thing to do is start out with an equation for acceleration, integrate to get a velocity equation, then integrate that to get a position equation.

anonymous · Answer

then use 

$$h(t)=-16t^2+v_0t+h_0$$ where $h_0$ is the initial height 
units are feet and seconds

anonymous · Answer

The only tricky part is to remember the constants of integration that come up. For your velocity equation, the constant will simply be your initial velocity. For the position equation, the constant is simple the initial position.

$$\frac{d^2x}{dt^2}=-9.8ms^{-2}$$

anonymous · Answer

thank you! just forgot what $$v _{0}$$ had to be multiplied by

anonymous · Answer

Don't use Satellite's equation if you're working with metric units.
