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 position of the ball above the ground. ... 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 x component is larger at C than at B; the y component at B points up while at C, it points downward. The x components are the same; the y component has a larger magnitude at C than at B. The velocity components are non-zero at B and zero at C. The x components are the same; the y component at C is zero m/s.
