This diagram represents the path of an object during projectile motion. The object is shot upwards on the left and hits the ground on the right. Focusing only on the vertical velocities at the five indicated points, label the diagram to make each statement true.
velocity at C > velocity at D > velocity at E
velocity at B is negative
velocity at C has the same magnitude as A but at A, the projectile is moving downwards
A parabolic path begins from the assumed ground level, rises vertically, reaches a peak, and then descends back to the same ground level. One data point is shown at the beginning ground level, one approximately two-thirds up to the peak, one at the peak, one approximately two -thirds of the way back down to the ground, and one at the end ground level.
