state position nature and size of an image when an object placed at an distance equal to its focal length of rear view in vehicles

The position nature and size of an image when an object placed at a distance equal to its focal length of rear view mirrors in vehicle will be

1) Position: Behind the mirror

2) Nature: Virtual

3) Size: Smaller than the object

Explanation:

Due to the nature and use of rear view mirrors, which are meant to enable the front facing driver visualize a wide area of the back portion of the vehicle, such that the images of the object will always remain smaller than the object, require a convex image

The image size, location, nature and orientation of an object placed in front of a convex mirror is diminished, behind the mirror of the upright, virtual, and upright

Therefore, the position nature and size of an image when an object placed at a distance equal to its focal length of rear view mirrors in vehicle will be

Position: Behind the mirror

Nature: Virtual

Size: Smaller than the object.

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
