p = mv PT = PT P1 + P2 = PI +P2 mv + 112 V2 = mv, +11212 1. 2A large truck has a mass of 18,000 kg and a velocity of 25 m/s to the right. What is the momentum of the truck? 2. A hot air balloon has momentum of 10,000 . If the velocity of the hot air balloon is 5 m/s going up, what is the mass of the hot air balloon? 3. Explain why a large freighter (large boat that carries cargo) that moves with a very low velocity has more momentum than a car that moves with a very high velocity. 4.. A 3000 kg truck moving with a velocity of 10 m/s to the right hits a 1000 kg car that is parked and has a velocity of 0 m/s. The impact causes the 1000 kg car to move with a velocity of 15 m/s to the right. What is the final velocity of the truck? 5. Two cars are in a collision. After the collision, they stick together (they have the same final velocity). Before the colision, the first car has a mass of 1200 kg with a velocity of 15 m/s to the right. The second car has amass of 1500 kg with a velocity of 12 m/s to the left. What is the final velocity of the cars? 6. Two masses in contact with each other are initially at rest (think about what this means for the initial momentum). The two masses then explode apart. The first mass of 30 kg moves to the left with a velocity of 10 m/s. The second mass has a mass of 20 kg. What is the velocity of the second mass
