When a ball bounces, it rises to $$\frac{2}{3}$$ of the height from which it fell. If the ball is dropped from a height of 36 m, how high will it rise at the third bounce ?
A. $$10\frac{1}{3}$$ m
B. $$10\frac{2}{3}$$ m
C. $$12\frac{1}{3}$$ m
D. $$12\frac{2}{3}$$ m
Answer: Option B
Solution(By Examveda Team)
Ball is dropped from the height of 36 m when the ball will rise at the third bounce∴ Required height :
$$\eqalign{ & = \frac{2}{3} \times \frac{2}{3} \times \frac{2}{3} \times 36 \cr & = \frac{{32}}{3} \cr & = 10\frac{2}{3}\,m \cr} $$
