A driver loses control of a car, drives off an embankment, and lands in a canyon 6.0 m below. What was the car's speed just before touching the ground if it was traveling on the level surface at 12 m/s before the driver lost control?

Hi there!

The horizontal component of the car's velocity (12 m/s) remains CONSTANT in the absence of air resistance.

Its vertical component of its velocity is being affected by gravity. We can use the kinematic equation:

vf = final velocity (? m/s)

vi = initial velocity (0 m/s)

a = acceleration due to gravity (9.8 m/s²)

d = displacement (6m)

Plug in the given values:

The speed is derived by using the pythagorean theorem as the above are simply the COMPONENTS of the total speed.

you go to your settings preference and in the end youll see sth that says "i want to delete my acc" click on it and u'll acc will be deleted but u have to wait.

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
