HELP ASAP DUE TODAY "In an elastic collision, an object with momentum 25kg⋅m/s collides with another object moving to the right that has a momentum 35kg⋅m/s. After the collision, both objects are still moving to the right, but the first object’s momentum changes to 10kg⋅m/s. What is the final momentum of the second object?"

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?
