At 3:00 P.M. a truck traveling on a winding highway has a velocity of 82.0 km/h [ E 38.2° N]; at 3:15 P.M., it has a velocity of 82.0 km/h [ S 12.7°E]. Assuming that +x is east and +y is north, determine the x- and y-components of the average acceleration during this time interval.

A plane flies 445 km east from city A to city B in 49.0 min and then 964 km south from city B to city C in 1.30 h. For the total trip, what are the (a) magnitude and (b) direction of the plane's displacement, the (c) magnitude and (d) direction of its average velocity, and (e) its average speed? Give your angles as positive or negative values of magnitude less than 180 degrees, measured from the +x direction (east). only need help on part E

A train at a constant 46.0 km/h moves east for 46.0 min, then in a direction 54.0° east of due north for 29.0 min, and then west for 56.0 min. What are the (a) magnitude and (b) angle (relative to east) of its average velocity during this trip?

A car is traveling west at 22.5 m / s when it turns due south and accelerates to 37.5 m /s, alt during a time of 4.00 s. what is the magnitude of the car's average acceleration
