A tennis ball is thrown upward at an angle from point A. It follows a parabolic trajectory and hits the ground at point D. At the instant shown, the ball is at point B. Point C represents the highest
-While in flight, how do the x and y components of the velocity vector of the ball compare at the points B and C?
A)The velocity components are non-zero at B and zero at C.
B)The x components are the same; the y component at C is zero m/s.
C)The x components are the same; the y component has a larger magnitude at C than at B.
D)The x component is larger at C than at B; the y component at B points up while at C, it points downward.
E)The x component is larger at B than at C; the y component at B points down while at C, it points upward.

In projectile motion, the horizontal (x) component of velocity remains constant, while the vertical (y) component changes due to gravity. At the peak (point C), the y component is zero.
