A 5.00 kg mass is at the origin. A 7.00 kg mass is located at x = 0.600 m,
and a 4.00 kg mass is at x = 0.900 m.
What is the net gravitational force on
the 5.00 kg mass?
[?] x 10' ?!N

heat the gas and measure the pressure

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
