Two objects with masses represented by m1 and m2 approach each other on a horizontal frictionless table with the same constant speed, v0, as measured by a laboratory observer. The objects undergo a perfectly elastic collision, and it is observed that after the collision, m2 moves off in a direction opposite its original motion with some constant speed v, and m1 is stationary.

(a) Determine the ratio of the two masses, m1/m2.

(b) Determine the ratio of their speeds, v/v0.

i would say the answer is food.

hope this !

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
