Answer:
7.30523 m/s
Explanation:
t = Time taken
u = Initial velocity = 0
v = Final velocity
s = Displacement = 2.72 m
g =  Acceleration due to gravity  = 9.81 m / s 2 = a
Equation of motion
v 2 u 2 = 2 a s v = 2 a s + u 2 v = 2 × 9.81 × 2.72 + 0 2 v = 7.30523   m / s
The speed which a quarter would have reached before contact with the ground is 7.30523 m / s
