Speed, being a scalar, is dependent upon the scalar quantity, distance. Velocity, being a vector, is dependent upon the vector quantity displacement. Now, can you answer the questions below? 3 km You ran from your house to a friend's house that is 3 km away in 30 minutes. You then immediately walked home, taking 1 hour on your return trip. What was your average speed (in km/hr) for the entire trip? What was your average velocity (in km/hr) for the entire trip?

A plane flying at 78.2 m/s [W32°S] takes 42 seconds to change its velocity to 78.2 m/s [S32°E]. a) Solve for the change in velocity of the plane algebraically, resolving vectors into their x- and y-components. b) What was the average acceleration of the plane over this time interval? c) Explain why the speed of the plane didn't change and yet the plane underwent acceleration. Please label sketches with events as well as GRASS and explanations to show your work. Please label triangle sides. Remember to have the magnitude rounded to a reasonable number of sig figs, the unit and the direction (if needed) in your answers.
