Falling from an airplane.
Positive charge=proton
Negative charge=electron
No charge/neutral=neutron
Because acceleration is constant, the acceleration of the car at any time is the same as its average acceleration over the duration. So

Now, we have that

so we end up with a distance traveled of


The ball rolled a distance of
d = 12m + 20m.
But the change of position is
x = + 12m - 20m
Answer: 83.3 W
Explanation: I think, I’m not sure. If I’m wrong correct me ;)
