Answer:2.26 seconds97m/sExplanation:1. Fall timei) Find the vertical speed of the plane when the tanks were releasedThat is the same initial vertical speed of the tanks.

ii) Find the fall timeOnly the positive value has aphysical meaning:

t = 2.26 seconds.2. Speed when they hit the groundi) The horizontal speed is constant:ii) The vertical speed is:iii) Total speed
