A bus travels 80 km due south in 2 hours it then travels 100 km due west in 3 hours what is the average velocity of the bus

Answer 1

Well, I can give you average
in 5 hours goes 80 km S and 100 km west
average east (x component ) = -20 km/h
average north(y component) = -16 km/h
average speed = magnitude of velocity = sqrt(400+ 256)= 25.6 km/h

Answer 2

What is the difference between radial and tangential acceleration?
