Use the Figure to Answer the Question $\theta$ )- ½ G (2

Multiple Choice

Use the figure to answer the question.
The figure represents the parabolic trajectory of a ball going from a to e in Earth gravity but without air resistance. The initial velocity of the ball is V_o at an angle to the horizon. The vertical dashed lines represent equal time interval,

-The vertical velocity at point b is: Note: (g = 9.81 m/s²)

A) 0
B) V_o cos ( $\theta$ ) - ½ g (2 $\Delta$ t) ²
C) V_o sin ( $\theta$ ) - ½ g (2 $\Delta$ t) ²
D) V_o sin ( $\theta$ ) + ½ g (2 $\Delta$ t) ²
E) V_o cos ( $\theta$ ) + ½ g (2 $\Delta$ t) ²
