#### Solution

(a) At all the points, the slope of the graph is constant.

∴ `veca` = constant

(b) No change in magnitude of the velocity with respect to time

∴ `vecv` = constant

(c) Slope of this graph is greater than graph (a) but constant

∴ `veca` = constant but greater than the graph (a)

(d) At each point-slope of the curve increases.

∴ `veca` is a variable and the object is in accelerated motion.
