An automobile travels on a straight road for 21 km at 23 km/h. Itthen continues in the same direction for another 21 km at 46 km/h.(a) What is the average velocity (in km/h) of the car during this42 km trip? (Assume that it moves in the positive x direction.) (b)What is the average speed (in km/h)?

A plane flies 477 km east from city A to city B in 48.0 min and then 980 km south from city B to city C in 1.50 h. For the total trip, what are the (a) magnitude (in km) and (b) direction of the plane's displacement, the (c) magnitude (in km/h) and (d) direction of its average velocity, and (e) its average speed (in km/h)? Give your angles as positive or negative values of magnitude less than 180 degrees, measured from the +x direction (east).

A car travels along a straight line at a constant speed of
60.0 mi/h for a distance d and then another distance d in
the same direction at another constant speed. The average
velocity for the entire trip is 30.0 mi/h. (a) What is theconstant
speed with which the car moved during the second
distance d? (b) What If? Suppose the second distance d
were traveled in the opposite direction; you forgot something
and had to return home at the same constant speed
as found in part (a). What is the average velocity for this
trip? (c) What is the average speed for this new trip?
