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 horizontal velocity at point c is A)0 B)V_o cos ($\theta$) C)V_o sin ($\theta$) D)V_o E)depends on what g is along the path

Question

Quizplus · Accepted Answer

At point c, the velocity vector has no vertical component, since the ball has reached its maximum height and is about to start falling downwards. Therefore, the horizontal velocity is simply the initial horizontal velocity, which can be calculated using the trigonometric component of the initial velocity: V_o cos (angle between the initial velocity and the horizontal, which is given as 11eca054_3c8a_5b29_a55c_4b66cd642b23_TB6079_11).
