then solve for v
so
so v = (3m/s^2)(6s)
so v = 18m/s

Answer:
Explanation:
The volume of the balloon can be find compared the force in each cases so:
reduce 25% from 74kg
So the net force uproad on the balloon is
Now the density of the both gases air and helium are different however the volume is the same change offcorss the mass so:
Answer:
- 4.77 %
Explanation:
We know that the volume V for a sphere of radius r is
If we got an uncertainty the formula for the uncertainty of V is:
We can calculate this uncertainty, first we obtain the derivative:
And using it in the formula:
The relative uncertainty is:
Using the values for the problem:
This is, a percent uncertainty of 4.77 %
