Homework Statement
Two stones are thrown simultaneously, one straight upward from the base of a cliff and the other straight downward from the top of the cliff. The height of the cliff is 6.00m. The stones are thrown with the same speed of 9.00 m/s. Find the location (above the base of the cliff) of the point where the stones cross paths.
Homework Equations
x = vot+ (1/2)at^2
vf=vo + at
vf^2 = vo^2 + 2ax
The Attempt at a Solution
x1 = vo1t + 1/2(-g)t^2; x2 = vo2t + 1/2(-g)t^2;
x1 + x2 = vo1t +vo2t - gt^2 = xtotal
? does vo1 = 9 m/s while vo2= -9 m/s? OR vo1 and vo2 = 9 m/s? If the latter, why?
