An astronaut standing on the moon of a distant planet throws a ball which then follows the parabolic trajectory shown in the sketch. The ball's position is shown at one second
intervals until t = 3 s. The ball's velocity is (1.651 + 1.657) m/s att = 1 s and it peaks at t=2s. Determine:
the balls velocity at t = 2 s; v2
att=3s; V3 =
î.
