1. Consider a ball being kicked at some angle with respect to the horizontal. Name three examples of possible vector quantities and three examples of possible scalar quantities associated with such an event. (You do not need to do any calculations.) (2 points) 2. In your own words, summarize why it is important to learn vector algebra. Your answer must include at least 2 complete sentences. (2 points) 3. On the left, the initial velocity vector, vo, is shown for a typical free fall projectile motion problem. On the right is shown the velocity vector, v, for some time later in the flight. The magnitudes of both vectors are listed in the table below. Calculate the lengths of each component. (Consider the x-component to refer to the horizontal direction, and the y-component to refer to the vertical direction. The angle specified in the table corresponds to the angle shown in the figure.) Show your work and record your answers in the table. (4 points) КК Vector Vo V Magnitude 45 62 Angle (degrees) 48 44 V₁ Length of x-component Length of y-component
4. A swimmer is able to swim with a speed of 5 m/s in a pool (this is her "water speed"). This same swimmer goes swimming in a river which has a current flowing to the East with a constant speed of 3 m/s. a. What would be her resultant velocity if she tries to swim due East with the current? Show all work and include a vector sketch. (2 points) b. What would be her resultant velocity if she were to try to swim due West against the current? Show all work and include a vector sketch. (2 points) c. What would be her resultant velocity if she points herself due North straight across the river? Show all work and include a vector sketch. (2 points)
