Physics - Kinematics Question with Solution | TestHub

Two identical pellet guns are fired simultaneously from the edge of a cliff. These guns impart as initial speed of $35.0\mathrm{m}/\mathrm{s}$ to each pellet. Gun A is fired straight upward, with the pellet going up and falling back down, eventually hitting the ground beneath the cliff. Gun B is fired straight downward. In the absence of air resistance, how long after pellet B hits the ground does pellet A hit the ground? $\left[\mathrm{g}=10\mathrm{m}/{\mathrm{s}}^2\right]$
