Motion in plane question

Solution

u = 2 \overset{⏞}{i} + 3 \hat{j} a = 0.3 \hat{i} + 0.2 \hat{j} A s v = u + a t v = (2 \overset{⏞}{i} + 3 \hat{j}) + (0.3 \hat{i} + 0.2 \hat{j}) t v = (2 \overset{⏞}{i} + 3 \hat{j}) + (0.3 \hat{i} + 0.2 \hat{j}) (10) v = 2 \overset{⏞}{i} + 3 \hat{j} + 3 \overset{⏞}{i} + 2 \hat{j} v = 5 \overset{⏞}{i} + 5 \hat{j} |v| = \sqrt{5^{2} + 5^{2}} = 5 \sqrt{2} u n i t s
