Question

On a windless day, two identical balls P and Q are dropped from the top and the middle of a tower at exactly the same time as shown .Which will be more: the time taken by P to reach the middle of the tower ,or the time taken by Q to reach the ground?

Answer 1

Answer: time is the same

Explanation: the distance(H) is the same in each case .

we drop the balls , no drag force using basic kimnematics

y =gt*t/2  , yo=0 , vo=0 , y=H  , so : t= sqrt(2H/g)

comment: if distance H starts to grow....we could begin to note a difference  because of gravity g is smaller as we go up
