Answer:
Explanation:
Given
Required
Determine the final mass
First we need to determine the total mass after the sample mass is added to an additional sample;
Next, divide the total mass by 3
The final mass is calculated as follows;
<em>Hence, the final mass is 17.560943085g</em>
Speed = distance / time
s = 550 / 4
s = 137.5 m/s
In short, Your Answer would be Option B
Hope this helps!
