an object of mass 800 gram hangs on a spring calculate the force exerted by the object of acceleration due to gravity is 10m/s square​

answer: a. same unit

explanation:

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
