What can you say about the velocity about the velocity of moving body that is dynamic equalibrium? draw a sketch of such a body using clearly label arrows represent all external forces on the body.

Equilibrium implies that the net force on the body is 0, therefore the body undergoes no acceleration. No acceleration means the velocity doesn't change.

The body's velocity stays constant over time.

newton's first law of motion

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
