a = f(x)
dv / dt = f(x)
(dx / dt)*(dv/ dx) = f(x)
v dv / dx = f(x)
so dx = vdv / f(x)
hence x = integral of (vdv) / f (x)
Hence Answer a is correct and
acceleration is directly proportionlal to velocity so acce. will not be constant
a = f(x)
so a / f(x) = 1
hencethe slope of acceleration versus velocity graph may may be constant
Hence Answer a and c is correct
