Mark all that apply. Which are factors that affect witness testimony? Race of the witness
Individual Evidence
Other witnesses
Use of Drugs

Knowledge of the crime

the answer would be c. motion and direction

i hope this : )

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
