Question

$y$ component of velocity is $20$ and $x$ component of velocity is $10$. The direction of motion of the body with the horizontal at this instant is:

• A. $\tan^{-1}(2)$
• B. $\tan^{-1}(1/2)$
• C. $45^{\circ}$
• D. $0^{\circ}$

Answer 1

Answer: (A)

$\tan^{-1}(2)$

Answer 2

According to the condition of question $\tan \theta =\frac{v_{y}}{v_{x}}=\frac{20}{10}=2$ $\therefore \theta =\tan ^{-1}(2)$
