Cannot do links sorry. A 112kg astronaut is tethered to the international space station (!SS) and is 26m from the center of mass of the ISS. The gravitational force between the astronaut and the ISS is 4.64 x 10^-6 N. Calculate the mass of the ISS.

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?

Gordon is going for a run through the park, but it is cold outside. the low outside temperature could affect his personal safety.

Acaterpillar tries to climb straight up a wall a meter high, but for every 2 cm up it climbs, it slides down 1 cm. eventually, it reaches the top. when it reaches the top, it does not pull itself over so it will slide down 1 cm. what is the total displacement traveled?
