A 2-kgtoy cartraveling initially with a speed of 30.0 m/s in an easterlydirection crashes into a5-kgtoy truck moving in the westdirection 20.0m/s. The velocity of the 2-kg car right after the collision is 15.0 m/s to the west. What is the velocity of the5-kgtruck right after the collision?

A 1 115.0 kg car traveling initially with a speed of 25.000 m/s in an easterly direction crashes into the back of a 10 000.0 kg truck moving in the same direction at 20.000 m/s. The velocity of the car right after the collision is 18.000 m/s to the east. Before After (a) What is the velocity of the truck right after the collision? (Give your answer to five significant figures.) 20.3 V m/s east (b) What is the change in mechanical energy of the car-truck system in the collision? Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. J (c) Account for this change in mechanical energy.

John’s 200-kg bumper car is traveling east at 10 m/swhen it collides head-on with Bob’s 180-kg bumpercar traveling west. After the collision, John’s cartravels west at 20 m/s while Bob’s travels east at 15 m/s. Determine Bob’s initial velocity.

A 3000-kg truck moving with a velocity of 10 m/s hits a 1000-kg parked car after which they stick together.  Determine their velocity immediately following the collision.
