Unformatted text preview: t = 1 s (which we feel is an acceptable modi±cation of the problem – since the datum t = 1 s is not used). (c) (a) (b) (d) Any change from zero to non-zero values of ~v represents in-creasing | ~v | (speed). Also, ~v k ~a implies that the particle is going faster. Thus, points (a), (b) and (d) involve increasing speed....
