A 623 kg car moving at 18.2 m/s in the +x direction hits from behind a second car moving at 10 m/s in the same direction. If the second car has a mass of 593 kg and a speed of 19 m/s right after the collision, what is the velocity of the first car after this sudden collision? Please show work and explain.
a) 26.8 m/s
b) 8.74 m/s
c) -9.63 m/s
d) 9.63 m/s

PROBLEM FUUR (20 FUL ) A 420 kg car moving at 14.4 m/s hits from behind another car moving at 11.3 m/s in the same direction. If the second car has a mass of 590 kg and a new speed of 17.9 m/s, what is the velocity of the first car after the collision?
A 1100 kg car traveling initially with a speed of 26.00 m/s in an easterly direction crashes into the back of a 9 450 kg truck moving in the same direction at 20.0 m/s. The velocity of the car right after the collision is 18.0 m/s to the east. (a) What is the velocity and direction of the truck right after the collision? (Give your answer to at least four significant figures.) (b) What is the change in mechanical energy...
A 1,245-kg car traveling initially with a speed of 25.0 m/s in an easterly direction crashes into the rear end of a 9,200-kg truck moving in the same direction at 20.0 m/s (see figure below). The velocity of the car right after the collision is 18.0 m/s to the east. (a) What is the velocity of the truck right after the collision? __________ m/s (east) (b) How much mechanical energy is lost in the collision? __________ J

A railroad car of mass 2.42 × 104 kg is moving with a speed of 3.84 m/s. It collides and couples with three other coupled railroad cars, each of the same mass as the single car and moving in the same direction with an initial speed of1.92 m/s.(a) What is the speed of the four cars after the collision?____ m/s(b) How much mechanical energy is lost in the collision?______J
A 2-kg block moving in the positive x direction with a speed of 5.0 m/s collides with a 3-kg block moving in the same direction with a speed of 2.0 m/s. After the collision the 3-kg block moves at 4.2 m/s. Find the velocity of the 2-kg block after the collision. Is the collision elastic or inelastic? Justify your answer.
A) If a 1552 kg car, moving at 8 m/s north, hits and sticks to a 1812 kg truck, moving at 6 m/s east, find the magnitude of the final speed. B) If a 1919 kg car, moving at 8 m/s north, hits and sticks to a 3187 kg truck, moving at 4 m/s west, find the direction of the final speed.
