An engineer designed a ball so that when it was dropped, it rose with each bounce exactly one-half as high as it had fallen. The engineer dropped the ball from a 20-meter platform and caught it after it had traveled 52.5 meters. How many times did the ball bounce?
Choose the correct option:
A) 5 B) 6 C) 7 D) 3 E) 2
Going down = 20 m   Going Up = 10 --&gt; Total = 30   Going down = 10 --&gt; Total = 40   Going Up = 5 --&gt; Total = 45   Going down = 5 --&gt; Total = 50   Going up = 2.5 --&gt; Total = 52.5 (Caught)   No of bouncing = 3   Answer : 3
