Problem

Match the following two columns :
Column IColumn II
(a) v=−2i^\mathbf{v} = -2\hat{i} , a=−4j^\mathbf{a} = -4\hat{j}(p) speed increasing
(b) v=2i^\mathbf{v} = 2\hat{i} , a=2i^+2j^\mathbf{a} = 2\hat{i} + 2\hat{j}(q) speed decreasing
(c) v=−2i^\mathbf{v} = -2\hat{i} , a=+2i^\mathbf{a} = +2\hat{i}(r) speed constant
(d) v=2i^\mathbf{v} = 2\hat{i} , a=−2i^+2j^\mathbf{a} = -2\hat{i} + 2\hat{j}(s) Nothing can be said
