Jane goes out for a run. She runs 10 miles West for 2 hours, then she stops suddenly and turns and runs North for 30 minutes while speeding up at a rate of 4.0x10-3 [m/s2]. She stops again, then runs with a constant velocity of 5[m/s] at 40 degrees North of East for 5 miles. HINT: you MUST draw a picture and choose a vector basis. a) Convert all quantities given to SI units. b) Write out the displacement vector for each leg of the trip in vector notation. c) Find Jane's average velocity for the entire run (magnitude and direction). d) Find Jane's average speed for the entire run.
