You are driving home from school steadily at 95 km/h for 130 km. It begins to rain and you slow down to 65 km/h. You arrive home after driving 3 hours and 20 minutes. (a) How far is
your hometown from school? (b) What was your average speed?

Aparticle moves in the xy plane with constant acceleration. at time zero, the particle is at x = 6 m, y = 8.5 m, and has velocity ~vo = (9 m/s) ˆı + (−2.5 m/s) ˆ . the acceleration is given by ~a = (4.5 m/s 2 ) ˆı + (3 m/s 2 ) ˆ . what is the x component of velocity after 3.5 s? answer in units of m/s.
