Two trucks of equal mass behave like rigid bodies. If a head-on collision between the two trucks is assumed to be perfectly elastic, which option BEST describes the post-collision situation? A) The slower trucks reverses direction but maintains the same speed.
B) The trucks exchange their speeds and reverse their direction of motion.
C) Both trucks start to move in the direction of the truck with higher speed.
D) The faster truck slows down to the speed of the slower truck but continues in the same direction.

C) Both trucks start to move in the direction of the truck with higher speed.

Explanation:

C) Both trucks start to move in the direction of the truck with higher speed.

Explanation:

The truck will move in the direction with the greatest momentum. Factors affecting momentum is mass & velocity (speed)

Hope this helps!

as technology advances, new experiments often expose problems in accepted theories. c

the first american roller coaster was the mauch chunk switchback railway, built in the mountains of pennsylvania in the mid-1800s. the track, originally built to send coal to a railway, was reconfigured as a "scenic tour."
