Ahelicopter lifts a 84 kg astronaut 19 m vertically from the ocean by means of a cable. the acceleration of the astronaut is g/15. how much work is done on the astronaut by (a) the force from the helicopter and (b) the gravitational force on her

Part a)

Part b)

Explanation:

Part a)

For the force equation of Astronaut we know that

so here we will have

as we know that

so we will have

Part b)

Gravitational force on her is given as

answer: (431,2)

step-by-step explanation:

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop
