Question 2 A ball is thrown from the ground with an initial velocity Vo. At the height of y = 1.8 m (from the ground level) its velocity is V = 4.8 î +8.5 ĵ (in m/s). a) Find its initial velocity, V, in unit vector notation. b) What is the total time-of-flight of the projectile? c) If this experiment is performed inside a huge elevator which is moving upward with a deceleration of magnitude 2.0 m/s², what happens? Discuss the situation.
