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. Just as they reach the lake below,

Answer 1

The velocity of Alice (25 m/s) will be greater than that of Tom (0), when they reach the lake below.

Step-by-step explanation:

Given;

initial horizontal velocity of Tom is zero since he dropped straight down from the edge.

initial horizontal velocity of Alice is 25 m/s.

Their respective horizontal velocity when they jumped is the same as when they reach the lake below.

If we compare their velocities when they reach the lake, one will be greater than the other, if we neglect air resistance.

Thus, the velocity of Alice (25 m/s) will be greater than that of Tom (0), when they reach the lake below.
