Pen and Teller decided to do a magic trick involving a marble and a ball. Penn throws the marble straight upwards from the ground with an initial velocity of v⃗ 0, marble=10 m/s j^. At the exact moment that the marble was released, Teller throws the ball with an initial velocity of v⃗ 0, ball=5 [m/s] i^+10 [m/s] j^. Which of the following is true about the two objects? Select one: a. The ball will reach the ground first. b. Both objects will reach the ground at the same time. c. The marble will reach a greater height. d. The ball will reach the ground last.

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
