Answer:

Explanation:
We have the following information,

We apply the equation for capacitor charging the voltage across it,

Replacing values,


Answer:
The answer here would be its "Magnitude".
Acceleration=9.81m/s^2
initial velocity=0m/s
time=.28s
We have to find final velocity.
The equation we use is
Final velocity=initial velocity+acceleration x time
Vf=0m/s+(9.81m/s^2)(.28s)
Vf=2.7468m/s
We would round this to:
Vf (final velocity)=2.7m/s
