Question

after 2 hours ,the displacement of the car is 150km north .the initial displacement of the car is 0.what ks the average velocity of the car?
I come back again 1pm
​

Answer 1

Answer:

75km/h due north

Explanation:

Simply use the formula displacement/time

Answer 2

Answer:

1250m/s or 1.25km/s is the average velocity.

Explanation:

Formula:

Average Velocity = Displacement/total time

Displacement = v - u

                       = 150 km or 150,000 m - 0

                       = 150 km or 150,000 m

Time = 2hrs = 120 seconds

Av. Velocity = 150/120

                    = 1.25km/s x 1000 [to convert into meters]

                    = 1250m/s
