From the slope of the image, we can know the value of a*v, MAV = Fv = P.

So we can find energy.

Because it is a straight line, the power of the whole process is constant.

When the acceleration is equal to zero, the traction is equal to the resistance, so that the maximum speed (the intersection of the image and the X axis) and the resistance (p/v) can be obtained.

If you use the differential equation of college physics, you can know the time, but because there is no study in high school, you can only find it by default.

Hope to adopt
