Suppose the student walks the following path: 20 M WEST, 25 M SOUTH, 8 M EAST, 9 M NORTH. Calculate the total distance the student traveled

Find the momentum for a 2.6-kg brick parachuting straight downward at a constant speed of 8.4 m/s .

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?

Acombination reaction is when two or more combine to form one product. a decomposition reaction is when a substance breaks down into two or more simpler substances in a chemical reaction.
