If a ball which is dropped from a height of 2.25 m on a smooth floor attains the height of bounce equal to 1.00 m, the coefficient of the restitution between the ball and floor, is

A 0.25

B 0.50

C 0.67

D 0.33

E 0.75

ANS:B - 0.50

V=√(2gh).
V is directly proportional to the √h.
C.r.=v2/v1
√(h2/h1).
