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
Answer:
Tilt = 23 1/2 (Florida Summer)
Tilt = 0
Tilt = 23 1/2
Tilt = 45
Tilt = 90
Explanation:
- From the most daylight to the least daylight the tilt of the planet on its axis will form the 23 and a half in the northern hemisphere that gets most of the sun and the equator as 0 degree has amp;e of sunlight through the day in north and south side and the winter again in the southern hemisphere as 23 and half degree.
- The angle of the 45 degrees s darkness as in the winter season and due to the titled nature of the axis and the distance from the sun. And the angle of 90 degrees again has darkness as the sun is too far and daylight becomes shorter with the extremes.
