Two coconuts fall from rest at the same time, one from a tree twice as high as the other.
1-If the coconut from the taller tree reaches the ground with a speed , what will be the speed (in terms of ) of the coconut from the other tree when it reaches the ground?
2-If the coconut from the shorter tree takes time to reach the ground, how long (in terms of ) will it take the other coconut to reach the ground?
