1. The given vector represents a hot air balloon that experiences a 0.25 m/s acceleration at an angle of 60° above the horizontal. 0.25m/sec^2 60 A. Draw the horizontal and vertical components of the vector.

PLEASE ANSWER THE FOLLOWING USING KEYBOARD (TEXT NOT HAND WRITING) Given a certain vector of arbitrary length, why is it useful to compute the unit vector of this vector?

Bruce begins 7 kilometers to the north of town and rides his bike along a straight trail which leads to a park 3km west of town. It takes him 20 minutes to cover this distance. Write a vector in component form that describes his ride while also finding the magnitude and direction of this vector. Also, find the component of Bruce's motion which is in the direction of SW using a unit vector that uses both forms of the dot product (algebraic and geometric), then write parametric equations expressing his motion with the town being represented by the origin and t=0 being his starting point. Using these equations, what is his position after 5 minutes? Then eliminate the parameter to get a rectangular equation for this linear path and verify algabraically amd graphically that this equation represents the line.

Is the following statement true or false? Explain. If the wind is blowing from the southwest, then the bearing for the wind vector is 225°. Choose the correct answer below. O A. The statement is true because a wind blowing from the southwest would cause the air to travel northeast, which would be a vector represented by a 225° angle. B. The statement is false because a wind blowing from the southwest would cause the air to travel northeast, which would be a vector represented by a 45° angle. C. The statement is false because southwest would be represented on the unit circle by a vector pointing into the middle of quadrant 1, which is a 45° angle. D. The statement is true because southwest would be represented on the unit circle by a vector pointing into the middle of quadrant 3, which is a 225° angle.

Knowledge Check: Drawing a Vector, Problem Please answer the following question(s): In this problem we practice drawing vectors that are combinations of other vectors. You will graphically combine the vectors 2A-1/2 B to find the resultant vector R. Find the resultant vector R=2A-1/2 B from the selection of vectors provided below. Place vectors at the location starting from the blue dot and keeping the order of addition as 2A-1/2 B. Finally, use the R the resultant vector starting from the blue dot. (The answer to this problem is on the next page, Drawing a Vector, Solution.) 1. Use the graphical method to construct the vector 8 R = 2A B 2. Place the vectors tail to head 3. Start from the point indicated in blue 4. Draw the resultant vector R -12 1/4 -8 -10 12 B A -6 -A -2 711 2 B 6 R 2 -2 2 4 6 8 10
