Physics · MOTION IN A PLANE

In the given parabolic path of a projectile shown in the figure, at the highest point of its trajectory, what are the vertical component of velocity (\( v_y \)) and the angle (\( \theta \)) made by the net velocity vector with the horizontal?

1. \( v_y = 0 \) and \( \theta = 0^\circ \)
2. \( v_y = v_o\sin\theta_o \) and \( \theta = 90^\circ \)
3. \( v_y = v_o\cos\theta_o \) and \( \theta = 45^\circ \)
4. \( v_y = -v_o\sin\theta_o \) and \( \theta = 180^\circ \)
