Which of the following steps would most likely result in lowering the force of a collision? a. increase initial velocity
b. increase mass
c. increase final velocity
d. increase collision time

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

at right angles to each other
