4. Two blocks with mass m,=200g and m,-400g, are coupled together and move to the right along a frictionless floor at 30 cm/s. A small explosive charge on one block goes off causing the 200g block to stop. After the explosion, what is the speed of the 400g block?

1. On a smooth surface, a 500-grams soft ball A at the velocity of 6 meters per second collides with another 200-grams ball B initially at rest. After collision, the two balls stick together and keep moving in the same direction as ball A. What is the velocity of the two balls after collision? Uj=6m/s >V1=V2 A m B m2
1.) A car (mass=400 kg) is traveling down a country road (speed is 10 m/s) when it collides with a deer (mass=200 kg) which is running in the opposite direction (speed is 2 m/s). The collision results in the deer getting stuck on the windshield. Treat this collision using the 'conservation of momentum' principle: a) Draw a sketch - label each MASS and each VELOCITY (with arrows for direction). b) Calculate the final speed of the car (remember the deer is stuck on top of the car) after collision (Note: they stick together to form a single mass)

Two blocks of mass 2.0 kg and 4.0 kg are pressed together, compressing a light spring between them. The spring, which has negligible mass, is not fastened to either block. When they are released simultaneously, they both moved freely on a horizontal smooth surface. The block of mass 2.0 kg will have more kinetic energy than the other block of mass 4.0 kg. III.
