Find the different velocitys of the plane..

Question

An airplane flying directly eastward at a constant speed travels 311 km in 2.0 h.

(a) What is the average velocity of the plane?

= ? km/h

(b) What is its instantaneous velocity?

= ? km/h

Answer 1

Velocity = Distance / Time

 

So the average velocity is V = 311 km / 2.0 h = 155.5 km/h

 

Since the speed is constant, the instantaneous velocity at any time t is also equal to 155.5 km/h
