A tennis ball (ball 1) is launched with a horizontal velocity of 30 m/s from a height of 2m above the ground, and its initial path is parallel to the ground. At the same time, another tennis ball (ball 2) is dropped from rest from an initial height of 2m. Ignoring air resistance,   a. True or false: Both balls will reach the ground at the same time   b. A third ball (ball 3) is launched with the same trajectory as ball 1, but its initial horizontal velocity is 15 m/s. Ball 3 will travel [just as far/half as far/twice as far] as far as ball 1 before hitting the ground
