Homework Statement
A rocket blasts off with constant acceleration straight upward. After 3 seconds the rocket is at a height of 80m. (a) what are the magnitude and direction of the rocket's acceleration? (b) what is its velocity at the time
Homework Equations
[itex] v=v_0+at [/itex]
[itex] v^2=V_0^2+2a\Delta x [/itex]
[itex] a=v^2-v_0/(2*x) [/itex]
[itex] x=x_0+v_0t+\frac{1}{2}at^2[/itex]
The Attempt at a Solution
None, because I was unsure how to proceed as using these equations would result in one unknown (either v or a)
