Question

has a mass of 54 kg, and their centers are sepalaled oy a distall+! What is the gravitational force between two students, John and Mike, if John has a mass of 81 kg, Mike has a mass of 93 kg, and their centers are separated by a distance of.62 m? Imagine a 4820 kg satellite in a geosynchronous orbit. If an 85 kg piece of space junk floats by at a distance of 3.5 m, what force will the space junk feel? s. 9. 10. With what acceleration will the space junk move toward the satellite? 11. With what acceleration will the satellite move (if any)? m/s2 m/s2

Explanation / Answer

Q8.

gravitational force=G*m1*m2/d^2

where G=gravitational constant=6.67*10^(-11)

m1=first mass=81 kg

m2=second mass=93 kg

d=distance between two masses=0.62 m

force=1.308*10^(-6) N

Q9.

force=G*m1*m2/d^2

where m1=4820 kg

m2=85 kg

d=3.5 m

force=2.2321*10^(-6) N

Q10.

acceleration=force/mass=2.626*10^(-8) m/s^2

Q11.acceleration of satellite=force/mass of satellite=4.63*10^(-10) m/s^2
