Two objects, A and B, have the same size and shape. Object A is twice as massive as B. The objects are simultaneously dropped from a high window on a tall building. (Neglect the effect air resistance.) And the objects reach the ground at the same time. Which of the following will be greater for object A?

There are 5 possbile other answer choices, thank you so much! Moves downward with 2.45 m/s^2 Moves upward with constant velocity  stays at rest moves downward with constant velocity moves upward with 0.48 m/s^2

A baseball is thrown vertically upward with an initial velocity of 9 m/s. Neglecting air friction, what will the speed of the baseball as it goes back to its original position/height? A) 20 m/s B) 4.5 m/s C) 9 m/s D) 15 m/s

An airplane flying horizontally with constant speed of 100 m/s, drops a box from height of 500 m above ground. How far from the release point will the box hit the m ground? Ignore air resistance. Take g = 10. a) 0 b) 500 m c) 5 km d) 1 km e) 2 km
