1. When a ball is dropped from a certain height it rebounds to 3/4 the part after hitting the ground. If ball is dropped from a height of 32 metre, to what height will it go in its third rebound ?

If a ball is dropped from a certain height it rebounds to 3/4 the part after hitting the ground. Original height = 32 metre After 1st rebound, height attained by the ball = $$frac{3}{4} imes 32 = 24$$ metre Similarly, after 2nd rebound = $$frac{3}{4} imes 24 = 18$$ metre $$ herefore$$ After 3rd rebound, the ball will reach = $$frac{3}{4} imes 18$$ = $$frac{27}{2} = 13 frac{1}{2}$$ metre
