projectile launch velocities, given a position
struggling with this problem:
using very simple projectile rules (no air resistance ect) and only gravity acting on the object, is it possible to:
with a known: gravity, launch magnatude and coodinates which the partical passes through, to work out the launch angle (or x,y components?)
using the position equations:
how do i find Vx and Vy?
itld be easy if i knew time, but i dont, however i do know magnatude.
anyone got any ideas?
