5ptsa car with mass m=1.42e3 kg is initially traveling directly east with a speed =25.0 m/s. it crashes into the rear end of a truck with mass =9000 kg moving in the same direction with speed =20.0 m/s. immediately after the collision the car has a speed =18.0 m/s in its original direction (the two do not stick together in this case). (a) what is the speed of the truck immediately after the collision?
m/s ( ± 0.2 m/s)
(b) the same two vehicles collide with the same speeds, but while the car is still traveling east the truck is going north when they collide, and this time they stick together. what is the speed of the car/truck combination just after the collision?
m/s ( ± 0.2 m/s)
(c) after the collision in part (b), in what direction is the combined wreckage moving? measure the angle in degrees away from due north.
degrees ( ± 0.1 degrees)
