Ball I launches from an elevated platform with an initial horizontal velocity (v₁) of 27 m/s and a initial height (h) of 120 meters; Ball II launches with an initial vertical velocity (v₁) of 80 m/s anc with a distance from the base of the platform d = 95 meters. Relative to when Ball I was shot, w should Ball II be shot so that the two balls collide in the air as Ball II is moving in an upward direction. Express your answer by filling in the following blank: Ball II must be launched seconds after Ball I launches. Round your final answer to the nearest thousandths place; do not enter units; (a = -g = -9.8 m/s).
