Answer:
Centripetal acceleration will be equal to
Explanation:
We have given time taken to cover 180° is 0.5 sec
So time taken by 360° is equal to = 2×0.5 = 1 sec
Radius of the circle r = 0.520 m
So distance
So velocity
We have to find the centripetal acceleration
Centripetal acceleration will be equal to
So centripetal acceleration will be equal to
I think you wrote 4900 twice so will use that as the distance. To solve this it is helpful to draw a picture. The drawing should be of a triangle. Since the driver is driving up at an angle, the 4900 ft will be the hypotenuse of the triangle. since we do not know the values of the other two sides of the triangle we cant solve for the altitude using Pythagorean theorem but we can solve using the sine function on our calculator. As sine of angle is equal to opposite over hypotenuse(sinθ=opposite/hypotenuse). Having θ and the hypotenuse we can solve for opposite or the altitude. using some algebra we get hypotenuse*sinθ=opposite or altitude. now to plug everything in and solve: 4900 ft*(sin(2°))=opposite or altitude=171 ft
The answer is B. They can only go through solid NOT liquid
<span><u>Answer
</u>
The size off the motorcycle.
<u>Explanation
</u>
A size of the motorcycle make it difficult for the drivers to judge its speed and distance. Is the speed is high the distance decreases very fast if the speed is low the distance decreases slowly. The small size of the motorcycle makes it so difficult to determine the speed and distance.
