A ball is thrown from a point with a speed ${v_o}$ at an angle of projection $\theta $. From the same point and at the same instant a person starts running with a constant speed ${v_o}/2$ to catch the ball. Will the person be able to catch the ball? If yes, what should be the angle of projection
A ball is thrown from a point with a speed ${v_o}$ at an angle of projection $\theta $. From the same point and at the same instant a person starts running with a constant speed ${v_o}/2$ to catch the ball. Will the person be able to catch the ball? If yes, what should be the angle of projection
Yes, ${60^o}$
Yes, ${30^o}$
No
Yes, ${45^o}$
A ball is thrown from a point with a speed ${v_o}$ at an angle of projection $\theta $. From the same point and at the same instant a person starts running with a constant speed ${v_o}/2$ to catch the ball. Will the person be able to catch the ball? If yes, what should be the angle of projection
Person will catch the ball if its velocity will be equal to horizontal component of velocity of the ball.
$\frac{{{v_0}}}{2} = {v_0}\cos \theta $
$⇒$ $\cos \theta = \frac{1}{2}$
$⇒$ $\theta = 60^\circ $
