Correct answer only ! answer the following questions using the velocity and time graph above. a. at what time(s) was the car stopped? b. at what time(s) was the car maintaining a constant velocity? c. at what time(s) did the car accelerate? d. at what time(s) did the car have a negative velocity?

A).  Stopped . . . . . 0.7 to 0.8 hours (velocity is zero)

B).  Constant velocity . . . . . 0.2 to 0.4 hours, and 0.7 to 0.8 hours, and also 1.0 to 1.1 hours  (velocity doesn't change as time passes)

C-pos).  Positive acceleration . . . . . Zero to 0.2 hours, and 0.8 to 1.0 hours  (velocity gets bigger as time passes)

C-neg).  Negative acceleration . . . . . 0.4 to 0.7 hours  (velocity gets smaller as time passes)

D).  Negative velocity . . . . . Nowhere on this graph  (velocity less than zero)

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
