answered-by-expert Expert Answer

The three equations of motion are:

1. v = u + at  
2. begin mathsize 12px style straight s equals ut plus 1 half at squared end style    
3. v2 - u2 = 2as
 
Here, s = displacement; t = time interval; u and v are initial and final speeds

These equations of motion hold true under the condition of uniform acceleration only.

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.
