There are competitions in which pilots fly small planes low over the ground and drop weights, trying to hit a target.

Part A

A pilot flying low and slow drops a weight; it takes $2\mathrm{.}8$ s

to hit the ground, during which it travels a horizontal distance of $190$ m

$.$ Now the pilot does a run at the same height but twice the speed. How much time does it take the weight to hit the ground?
