Answer:19.5 m
Explanation:
Given
coefficient of kinetic Friction
Initial speed
Friction is present so it tries to stop to the object and stops it completely after moving certain distance let say s
maximum deceleration provided by friction is
using equation of motion
where
A concave mirror is curved inward in the middle, more
like a cave. Because the mirror is curved inward, the angle of the light
surface can be focused similar to that of the camera. They can form real images
that are projected out in front of the mirror at the place where light focuses.
When the object is located at the center of the curvature the image formed will
also be at the curvature. The image will be inverted and the magnification
value is equal to 1 which will become a real image because the ray of light
converges at the location of the formed image.
