Sam is standing on a balcony while holding two objects. She reaches over the railing and drops object A from a height of 20.0 m above the ground. 0.3 seconds later, she throws object B directly upward with a speed of 4.00 m/s. One second after she dropped object A, the velocities of the objects are measured. At that time, find: a) Object A’s velocity relative to the Earth b) Object B’s velocity relative to the Earth c) Object B’s velocity relative to Object A  d) Object A’s velocity relative to Object B
