Wiley Coyote and his Acme rocket, together having inertia of 1000kg, are speeding after roadrunner. Upon seeing a large brick wall, he tries to slow down. Unfortunately, he's still going 5m/s when he runs into the wall. The wall is not affected, but the rocket crumples (the coyote hangs on), such that the center of mass of the rocket/coyote travels 50 cm between striking the wall and coming to rest. (only consider horizontal motion)
-What is the change of the center of mass of the rocket/coyote combination?
-What is the total work done by the wall on the rocket/coyote system?
-What is the magnitude of the average force on the rocket/coyote system?
