A steel ball is thrown up from the top of a tower of height 115 m with a velocity of 50 m/s . While coming down, it strikes a glass pan, held at half the height of the tower from the ground and loses 35% of its velocity in breaking the glass. Determine the time taken to reach the maximum height and the velocity with which it will strike the ground and total time taken to reach the ground. The time taken to reach maximum height in seconds is? The maximum height reached in m is? The time taken by the steel ball from maximum height to the glass pan in seconds is ? The velocity of the steel ball when it hits the glass pan in m/s is ? The velocity of the steel ball when it hits the ground in m/s is ? The total time taken by the steel ball in seconds is?
