Answer:
The apparent weight of the pilot is 3311 N
Explanation:
Given;
radius of the vertical circle, r = 600 m
speed of the plane, v = 150 m/s
mass of the pilot, m = 70 kg
Weight of the pilot due to his circular motion;
Real weight of the pilot;
Apparent weight - Real weight of pilot = weight due to centripetal force
Therefore, the apparent weight of the pilot is 3311 N
Yes. Your answer is correct. I hope you do well on the quiz or whatever it is.
Answer:
After all, "Spring Tides" (peak ocean tides that arise bi-monthly) occur when the Sun, the Moon and the Earth are nearly in a straight line around the times of the New Moon and Full Moon.
Explanation:
Answer:
- <u>Because in both kind of motions, the position is periodically repeated. Both are simple harmonic motions.</u>
Explanation:
<em>Moving back and forth</em> means that the moving object goes through the same position every time a certain period of time elapses.
The same is true for the <em>circular motion</em>, every time the object completes a turn, the object is in the same position.
They are examples of simple harmonic motions. The time it takes the object to repeat a complete cycle is called period.
Therefore, in a grahp of position versus time, the curve that represents the position repeats itself every so often equal to one period, both for moving back and forth and for moving in a circle.
Answer:
Explanation:
velocity of vehicle u = 20 m/s
acceleration a = 22 m /s²
distance s = 170 m
time t = ?
s = ut + 1/2 a t²
170 = 20 t + 1/2 x 22 t²
170 = 20t + 11 t²
11 t² + 20 t - 170 = 0
t = 3 s
