Physics - NLM Question with Solution | TestHub

Here, m = 0.2 kg ; u = 0

$\overrightarrow{\text{F}}=\left(\text{0.3}\widehat{\text{i}}-\text{0.4}\widehat{\text{j}}\right)\text{N}$

$\overrightarrow{\text{v}}=\text{?}\text{, }\text{t}=6\text{s}$

$\overrightarrow{\text{a}}=\frac{\overrightarrow{\text{F}}}{\text{m}}=\frac{\left(\text{0.3}\widehat{\text{i}}-\text{0.4}\widehat{\text{j}}\right)}{\text{0.2}}=\frac{3}{2}\widehat{\text{i}}-2\widehat{\text{j}}$

From$\overrightarrow{\text{v}}=\overrightarrow{\text{u}}+\overrightarrow{\text{a}}\text{t}\text{, }\overrightarrow{\text{v}}=0+\left(\frac{3}{2}\widehat{\text{i}}-2\widehat{\text{j}}\right)\times 6$

$=9\widehat{\text{i}}-12\widehat{\text{j}}$
