Question 10.3 Prove that the CM of two particles lies on the line joining the particles and between them.

8.3 please!  1. Find the x component of the net momentum of the particles if we define the system to consist of A and C. 2. Find the y component of the net momentum of the particles if we define the system to consist of A and C. 3. Find the x component of the net momentum of the particles if we define the system to consist of B and C. 4. Find the y component of the net momentum of the particles if we define the system to consist of B and C 5. Find the x component of the net momentum of the particles if we define the system to consist of all three objects. 6. Find the y component of the net momentum of the particles if we define the system to consist of all three objects.

A knife thrower throws a knife toward a 300 g target that is sliding in her direction at a speed of 2.30 m/s on a horizontal frictionless surface. She throws a 22.5 g knife at the target with a speed of 38.0 m/s. The target is stopped by the impact and the knife passes through the target. Determine the speed of the knife (in m/s) after passing through the target.

Two pieces of space debris drift toward each other, collide, and stick together. The first piece has a mass of 45 kg and a velocity of m/s just before the collision. The second piece has a mass of 65 kg and a velocity of m/s just before the collision. What is the velocity of their center of mass after the collision? O ( 0.73, 0.73, 4.95 ) m/s O ( 3.27, 3.27, 4.05 ) m/s O ( 9.00, -5.00, 9.00 ) m/s O ( -0.99, -0.99, 11.50 ) m/s O None of the above
