Two experiments are performed with two trolleys that have the same mass. The moving parts of the trolleys are frictionless, and the surface on which they travel is also frictionless. In both experiments, trolley X travels towards trolley Y, which starts at rest. Following the collision in experiment 1, X is at rest and Y moves away to the right. Following the collision in experiment 2, the trolleys stick together and move away as one. What types of collision occur in these experiments?
- Aexperiment 1: elastic, experiment 2: elastic
- Bexperiment 1: elastic, experiment 2: inelastic
- Cexperiment 1: inelastic, experiment 2: elastic
- Dexperiment 1: inelastic, experiment 2: inelastic
