A steel ball is thrown up from the top of a tower of height 80 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 30% 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.
