So i was googling the mighty google for a general question on velocity and i happened upon this equation with no description of it. Only states it is a velocity equation
velocity=sqrt((-g)(horizontal distance)/sin(2theta))
sorry, symbols is not working on me laptop at the moment
Its been a LONG while since physics for me but i do not recal this equation.
an example was given of:
distance a ball was thrown = 290 feet
g= -32
angle ball was thrown was 26* ( i assume horizontal is 0* but sin 0 = o which can't have in denominator so something seems odd)
they end up with roughly 108.52 ft/sec
this eq seems strange to me. i threw a ball at roughly 8* and it took 1.002 seconds to go 15feet. if i plug that into me equation i get 42 feet/s
that doesn't sound right to me because after 1.002 seconds, the ball landed at 15 feet, so it can't be going 42 feet/sec then.
ANYWAY my MAIN QUESTION IS... WHAT EQUATION IS THIS HAHAHA
thanks
