Horizontal Launch
Part of the Mechanics section of Coddy's Physics journey. Lesson 34 of 94.
Launched horizontally, an object starts with zero vertical velocity. The height sets the time; the launch speed sets the distance:
h = ½ g t², x = v0 t
The horizontal part of the velocity stays the same; only the vertical part grows.
The horizontal part of the velocity stays v0; only the vertical part grows.
Challenge
A diver runs straight off a cliff, moving horizontally, and falls 44.1 m to the sea. Find the time t of the fall.
