Jill's dog Sparky runs 50.0 m northeast to a tree, then 90.0 m west to a second tree, and finally 30.0 south to a third tree.  Draw a picture and establish a coordinate system.  Calculate the x component (in m) of Sparky's net displacement.  Calculate the y component (in m) of Sparky's net displacement.  Calculate the magnitude (in m) of Sparky's net displacement.

QUESTION 2 Which of the following is an accurate statement? O A. It is possible to add a scalar quantity to a vector. O B. Even though two vectors have unequal magnitudes, it is possible that their vector sum is zero. OC. Rotating a vector about an axis passing through the tip of the vector does not change the vector. OD. The magnitude of a vector is independent of the coordinate system used. O E. The magnitude of a vector can be zero even though one of its components is not zero.

m Let B = 5.05 m at 60.0°. C and A have equal magnitudes. The direction angle of Ĉ is larger than that of A by 25.0°. Let A · B = magnitude . . 29.1 m² and B C = 36.3 m². Find the magnitude (in m) and direction (in degrees) of A. direction
