- Vector v = <-4,4>. Draw the vector 1.5v and give its component form and its magnitude and direSolve the following problem using analytical techniques: Supponn you walk 16.0 m straight west and then 25.5 m stralght north. How far are you from your starting point, and what is the compass direction of a line connecting your starting point to your final position? (I you represent the two Ings of the walk as vector displacements A and B, as in the figurn hrlow, then this problem asks you to find their sum R AB. Give the direction in degrees north of west.) A +B-R N RWhich of the following statements are correct? Adding two vectors creates a new "resultant" vector. When adding parallel vectors, the resultant vector is the sum of the magnitudes of the original vectors. When adding perpendicular vectors, the resultant vector is the sum of the magnitudes of the original vectors. Graphing calculators always report angles in degrees. Vectors pointing in different direction cannot be subtracted. A vector can be broken into x and y component vectors that sum to equal the original vector. Multiplying a vector by a scalar changes the vector's magnitude and direction.
- Can you answer problem 2? Can you also provide a short explanation for the answer you chose?The Maton family begins a vacation trip by driving 710 km west. Then the family drives 610 km south, 310 km east, and 410 km north. Where will the Matons end up in relation to their starting point? Give direction only, directly East is 0 degrees and the order goes counter clock wise (North is 90 degrees, West is 180 degrees, South is 270 degrees).Problem 3.3 Prove that the components of a vector with respect to a given basis are unique.

- kindly answer it immediately -A cross country skier 7.40 km in the direction 30 degrees west of south, then 2.80 km in the direction 45 degrees north of west, and finally 6 km in the direction 22 degrees east of north. To then return to his starting point, how far and in what direction must he travel? -A person who is 35 ft east of you runs north at 16 ft/s. At what angle north of east would you throw a ball at 60 ft/s groundspeed in order to hit him? -What is the kinetic energy of a 3000 lb automobile which is moving at 30 mi/h?Solve the following problem using analytical techniques:Suppose you walk 18.0 m straight west and then 25.0 mstraight north. How far are you from your starting point, andwhat is the compass direction of a line connecting yourstarting point to your final position? (If you represent the twolegs of the walk as vector displacements A and B , then this problem asks you to find their sumR = A + B .)Note that you can also solve this graphically.
