Answer:

Explanation:
The first number is
.
The second number is
.
We must multiply these two numbers together.

In scientific notation: 
Therefore, this is the solution you are looking for.
Response:
The stone's velocity is 2.57 m/s.
Clarification:
Provided that
Height = 0.337 m
We need to determine the velocity of the stone
Using the motion equation

Where, v = velocity of the stone
u = initial velocity
g = gravity's acceleration
h = height
Substituting into the formula



Thus, the stone's velocity is 2.57 m/s.
