Acar travels in a straight line from a position 50 m to your right to a position 210 m to your right in 5 sec. a. what is the average velocity of the car? b. construct a position vs. time graph and calculate the slope of the line of best fit.

The average velocity of the car is 32 m/s.

Explanation:

Given that,

Initial position = 50 m

Final position = 210 m

Time = 5 sec

(a). We need to calculate the average velocity of the car

Using formula of average velocity

Put the value into the formula

(b). We need to draw the position vs. time graph

We need to calculate the slope of the line of best fit.

Using formula of slop

Put the value into the formula

Hence, The average velocity of the car is 32 m/s.

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
