The acceleration of the box is approximately
Explanation:
According to Newton's second law of motion, the net force acting on the box is equal to the product between its mass and its acceleration:
where
is the net force
m = 12.0 kg is the mass of the box
a is the acceleration
The net force can be written as
where
is the applied forward force
is the friction force
Combining the two equations,
And solving for the acceleration,

Our team is having a really hard time trying to decode the gibberish
in the question, but they do seem to be picking up a message that
you're in an exam. If that's true, then thank you for taking some of

Now turn off your phone and drag your attention back to the exam.
Since direction is part of velocity, and the object is moving in a circle, its velocity is constantly changing.
Use the formula 1/2*I*w^2 where w is the angular speed and I is the rotaional inirtia (for disk it is .5*mass*radius^2).
A single electron has a charge of
Therefore, if we have an excess of
electrons, the total net charge will be the product between the charge of a single electron and the total number of electrons in excess:
