Two experiments are performed using two trolleys with equal masses. Every moving part of each trolley is frictionless, and the surface over which they travel is also frictionless. In both experiments, trolley X travels towards trolley Y, which is initially at rest. Following the collision in experiment 1, X comes to rest and Y moves away to the right. Following the collision in experiment 2, the trolleys stick together and move away as one. What kinds 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
