Outside the space shuttle, you and a friend pull on two ropes to dock a satellite whose mass is 700 kg. the satellite is initially at position < 3.3, -1.6, 2.0> m and has a speed of 6 m/s. you exert a force < -400, 500, 250> n. when the satellite reaches the position < 2.3, 2.6, -11.8> m, its speed is 6.18 m/s. how much work did your friend do?

your friend did a work of 1717.34 J

Explanation:

The sum of the work made by your friend and you is equal the change in the kinetic energy, so:

Where is the work that you did, is the work that your friend did, m is the mass of the satellite and and are the final and initial speeds

Additionally the work that you did is equal to:

Where F and s are vectors. So, the vector s that said the displacement is calculated as:

s = <2.3, 2.6, -11.8> - <3.3, -1.6, 2.0>

s = <-1 , 4.2 , -13.8>

Therefore, is:

Then, replacing the values on initial equation and solving for , we get:

Finally, your friend did a work of 1717.34 J

hail is a solid form of precipitation composed of large, layered ice particles called pellets that often have spherical shapes. this phenomenon occurs during thunderstorms in the could type known as cumulus

hope this you out ^w^

not too sure thinking it will always be directed towards the centre of the earth. could be wrong not sure
