A street car moves from station $A$ (stops) to the next station $B$ (stops) with acceleration $f = a - b x$ , where $a, b$ are positive constants and $x$ is the distance from $A$ . The distance between the stations and the maximum velocity are:

Options:

Answer:

Solution:

$v d v / d x = a - b x$ gives $v^{2} = 2 a x - b x^{2}$ , zero again at $x = 2 a / b$ . Maximum at $x = a / b$ : $v^{2} = a^{2} / b$ .
