Please help me answer these questions!! ASAP 1. Three collisions are elastic and three are inelastic. Determine which collision type took place for each collision support your conclusion with a data and observations from the lab.
2. Using your data how are you able to determine if conservation of momentum occurs in each collusion?
3. Write a conclusion for this lab also make sure to discuss the conservation of momentum and how it applies to collisions.

11. you want to calculate the displacement of an object thrown over a bridge. using -10 m/s2 for acceleration due to gravity, what would be the total displacement of the object if it took 8 seconds before hitting the water?

Acave rescue team lifts an injured spelunker directly upward and out of a sinkhole by means of a motor-driven cable. the lift is performed in three stages, each requiring a vertical distance of 10.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.90 m/s; (b) he is then lifted at the constant speed of 4.90 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 68.0 kg rescue by the force lifting him during each stage?
