1. A ten year old boy (26 kg) sits on a wheeled office chair (16 kg) holding a fire extinguisher (18 kg when empty). He points the discharge horn to the right and ejects all 9 kg of the carbon dioxide at 20 m/s. What is his velocity after the fire extinguisher is emptied (assuming friction is negligible)? 2. A group of students are performing an experiment in class using collision carts on a track. An 8.0 kg cart moving to the right at 4.0 m/s hits a 4.0 kg cart moving to the left at 6.0 m/s. Immediately after the collision, the 4.0 kg cart moves to the right at 3.0 m/s. What is the velocity of the 8.0 kg cart after the collision? I 3. A 2600 kg SUV traveling west at 15 m/s collides head on with a 1300 kg sedan traveling east at 20 m/s. Determine the speed and direction of the two cars immediately after impact if they lock together. 4. A 136 kg defensive lineman is about to tackle a 100 kg quarterback. Right before impact, the lineman is moving north at 6.0 m/s and the the quarterback is moving north at 1.0 m/s. Determine the speed and direction of the two players immediately after the tackle. 5. Two adjacent students stand on stationary skateboards, face each other, and push apart. The skateboarder on the left weighs 65 kg, the one on the right is 85 kg. If the lighter skateboarder moves at 3.2 m/s, determine the speed and direction of the heavier skateboarder. Fo 1.
