How dose newton’s first law describe

-Newtons first law is known as the law of motion

-newtons first law states that an object will remain at rest or in constant motion unless acted on my a force.

- newtons first law mainly involves forces , keep in mind ( friction ,gravity)

b would be the answer

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
