A 25000 kg truck moving at 40 m/s on a road angled at 17° hits a 10000 kg van moving at 25 m/s on a road angled at 60° at an intersection between two the two roads. Since this is a two-dimensional perfectly inelastic collision, what is the final velocity of the wreck?
Not sure about which...
Our prof gave us a hint and told us to call the position Xf. He indicated that the answer was right under our noses.
Which led me to believe that there was some deception involved.
The escape velocity on Planet X is the speed the rocket needs in order to never fall back down again in a universe in which X is the only object. In order for the rocket to not fall back down, its velocity to never become negative, how far away does the rocket have to be when the velocity is 0...
