begin mathsize 11px style Initial space velocity space equals space straight u Final space velocity space equals space 1 fourth straight u Acceleration space equals space minus straight a straight v space equals space straight u space plus space at 1 fourth straight u space equals space straight u space plus space at minus 3 over 4 straight u space equals space minus at rightwards double arrow straight t space equals space fraction numerator 3 straight u over denominator 4 straight a end fraction end style

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.
