During its descent, the pair of sunglasses passed by a climber in the canyon 6 seconds after stefano dropped them. to the nearest meter, what is difference in elevation between stefano and the climber?

166 meters
176 meters
230 meters
240 meters

Step-by-step explanation:

This is more like Physics and the pull of gravity, but no matter.  The equation for this (at least the one I used) is

Δx = v₀t + .5at²

where Δx is the displacement of the glasses, v₀ is the initial upwards velocity of the object, a is the acceleration due to gravity and t is time in seconds.

We are solving for Δx, our initial upwards velocity is 0 since the object didn't travel upwards in a parabolic arc but fell straight down, the acceleration due to gravity is -9.8 m/sec/sec, and t is 6 sec.  Filling in:

Δx = .5(-9.8)(6)² which simplifies to

Δx = .5(-9.8)(36) which means that

Δx = -176.4 or just -176

The Physics part of that means that the negative is due to the fact that object fell below the point from which it was released.

You may be using a parabolic equation in math, but this equation in physics is the exact same equation.

v: l•w•h÷2.

v: 20•6•8 ÷2

v: 960÷2

v: 480
