Explanation:
Answer:
Maximum speed, v = 36 m/s
Explanation:
Given that,
The radius of the curved road, r = 120 m
Road is at an angle of 48 degrees. We need to find the maximum speed of stay on the curve in the absence of friction. On a banked curve, the angle at which it is cant is given by :

g is the acceleration due to gravity


v = 36.13 m/s
or
v = 36 m/s
So, the maximum speed to stay on the curve in the absence of friction is 36 m/s. Hence, this is the required solution.
A convex lens makes light rays converge (come together) at the focal point or focus. The distance from the center of the lens to the focal point is the focal length of the lens. Convex lenses are used in things like telescopes and binoculars to bring distant light rays to a focus in your eyes.
