Answer:
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.
The difference in elevation between Stefano and the climber will be 176 meters. Then the correct option is B.
Let a be the acceleration, u be the initial velocity, v be the final velocity, and t be the time.
Then the equation of motion is given as,
s = ut + (1/2)at²
During its descent, the pair of sunglasses passed by a climber in the canyon 6 seconds after Stefano dropped them.
Then the difference in elevation between Stefano and the climber will be
s = 0 + (1/2)(9.8)(6²)
s = 176.4
s ≈ 176 meters
Then the correct option is B.
