12. An electron, starting from rest, has an acceleration that in- creases linearly with time; that is, a = kt, in which k = 1.50 m/s. (a) Plot a versus t during the first 10-s interval. (b) From the curve of part (a) plot the corresponding v versus t curve and estimate the electron's velocity 5 s after the motion starts. (c) From the v versus t curve of part (b) plot the corre- sponding x versus t curve and estimate how far the electron moves during the first 5 s of its motion. X
