answered-by-expert Expert Answer

In mechanics, u represents initial velocity and v represents final velocity.

In optics: u represents object distance i.e., the distance of the object from the pole of the mirror/optical centre of the lens.

And v represents image distance i.e., the distance of the image from the pole of the mirror/optical centre of the lens.

question 1) A body is projected vertically upwards from top of the tower with the velocity of 30m/s. if it takes 8sec to reach on ground then what is the height of the tower (g=10ms). what is the total distance travelled by the body. question 2) A body is dropped from the height of h covers by 64% distance in its last second.find out thte total tim of the ball and height. question 3) A body projected vertically upward, At the half  of its maximum height its velocity becomes 20m/s, what is the maximum height attained by the body. question 5) A body is projected vertically upward from ground. the time of flight is 8 sec find the velocity of projection.
