Question

A dog walks with an average velocity of 1.5 m/s for 10.0 seconds. What is the magnitude of the dogs displacement?

Answer 1

Distance

Speed = ----------------

Time

Distance/Displacement

1.5m/s = ------------------------------------------

10s

Distance

1.5m/s × 10 = --------------------- × 10

10s

(Get rid of the fraction by multiplying it by the denominator in this case 10)

15m = Distance

Distance and Displacement are almost the same thing regarding this question. But watch out when you doing other questions and when you have initial velocity and initial time.

Displacement is 15m.
