Expert Solution
Step 1

When any object having whatever mass falls from a height in a vacuum (No air resistance) the it experiences a constant acceleration , that is acceleration due to Earth's force of gravity  g=9.8 mS2.

So, Here both the object having different mass will fall at a constant acceleration.

 

Now as the falling object experience gravitational force , it accelerates, so its speed changes with time while falling. So no constant speed for the falling crates.
