student throws a heavy red ball horizontally from a balcony of a tall building with an initial speed v0. At the same time, a second student throws a lighter blue ball horizontally from the same balcony with an initial speed v0 /2. Ignoring air resistance, which of the following statements must be true? a. The red ball hits the ground with the greater speed. b. Both balls hit the ground with the same vertical velocity component. c. Both balls hit the ground with the same angle of impact d. The balls reach the ground at the same instant.
