A helicopter lifts a 78 kg astronaut 10 m vertically from the ocean by means of a cable. The acceleration of the astronaut is g/10. How much work is done on the astronaut by (a) the force from the helicopter and (b) the gravitational force on her? Just before she reaches the helicopter, what are her (c) kinetic energy and (d) speed?

A space habitat for a long space voyage consists of two cabins eachconnected by a cable to a central hub. The cabins are set spinningaround the hub axis, which is connected to the rest of thespacecraft to generate artificial gravity.

(a) What forces are acting on an astronaut in one of thecabins?

(b) Write Newton's second law for an astronaut lying on the "floor"of one of the habitats, relating the astronaut's mass m, hisvelocity v, his radial distance from the hub r, and the normalforce n.
Newton's 2nd Law= ?
Normal Force= ?

(c) What would n have to equal if the 65.0-kg astronaut is toexperience half his normal Earth weight?
