Question
A ball is thrown from a height of 900 m on the ground. It bounces (2/3) times of its every last bounce. Find the total distance covered by the ball till that ball stops?
⇒ 900, 600, 600, 400, 400, ............ x (series not formed) Total distance covered ⇒ (900 + 600), (600 + 400) ⇒ 1500, 1000, ........ (proper series) 500 = a/(1-r) ⇒ 1500/(1-2/3) ⇒ 4500More Arithmetic Progression Questions
