Answer:
The value is
Explanation:
Generally the relative speed at which you are moving with respect to the person ahead of you is mathematically represented as

substituting 1.05 m/s for
and 2.75 m/s for 
So

=>
Generally the distance by which the person is ahead of you is mathematically represented as

substituting 18.5 s for

=> 
(35/g) = mass of 3.57kg. (9.8 for g).
<span> (35 x 0.75) = 26.25N. friction.
</span><span> (246 - 26.25) = net 219.76N. accelerating force.
</span><span> Aceleration = (f/m) = (219.76/3.57) = 61.56m/sec^2</span>
There will be no way that to happen aton is a positive charge
With time, momentum increases as it builds speed assuming their is nothing in the way to stop it. Based on the graph, you can see that example being displayed as the line on the graph gets higher
D the resistance will increase. And it will cause current to decrease
