3. Your dog is dragging you with a force of 100 N at an acceleration of 4 m/s2, what is your mass?

question1

1,000 tons

question2

3: 8

question 3

store d

step-by-step 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
