Distance covered by an elevator = 310 feet.
Time taken to cover 310 feet = 10 seconds.
The rate of the elevator at its run = 310/10 = 31 feet per seconds.
We're trying to find at how many feet an elevator can travel in 12 seconds.
In order to find the distance covered by an elevator in 12 seconds, we need to multiply 12 by the rate of the elevator.
<em>Thus, distance covered by the elevator in 12 seconds = 12 × 31 </em>
= 372 feet.
The free body diagram consists of:
1) Weight force, which is a vertical arrow downward
2) A Normal force that is perpendicular to the ramp.
The Normal force can be decomposed in a vertical component and an horizontal component.
The vertical component, Ny, must equal the weight force, due to equilibrium (rest) condiition =>
Ny = weight = m*g = 5.5kg*9.8m/s^2 = 53.9 N
By geometry the vertical component of the Normal force, Ny is such that
cos (angle) = N / Ny => N = Ny * cos(angle)
=> N = 53.9N * cos(angle)
Now use that equation for each option:
a) 0 ° => N = 53.9N * cos(0) = 53.9N
b) 12° => N = 53.9 * cos(12) = 52.7N
c) 25° => N = 53.9 * cos(25) = 48.9N
d) 45° => N = 53.9 * cos(45) = 38.1N
When dealing with the degree of cyclones we have to consider the place where a cyclone can occur.
<h3>Why does a Grade 1 cyclone have more consequences?</h3>
This is due not only to the degree of the cyclone but where it occurs, so a cyclone of degree 1 in a city will have infinitely greater consequences than a hurricane of 5 in the middle of the ocean.
