Question

Alice and Tom dive from an overhang into the lake below. Tom simply drops straight down from the edge, but Alice takes a running start and jumps with an initial horizontal velocity of 25 m/s. Neither person experiences any significant air resistance. Compare the time it takes each of them to reach the lake below.

Answer 1

Since both start with the same vertical velocity from the same position with the same acceleration they will reach the lake at the same time.
