Activități de învățare și autoevaluare 1) În figura III.18 sunt reprezentate punctele cardinale, vitezele a trei

mobile și scara folosită (unui segment îi corespunde o viteză de 10 km/h).

Precizează caracteristicile vitezelor v2 și v3 ghidându-te după exemplul

dat pentru vị. (Exemplu: vị are direcția Nord-Sud, sensul spre Sud și mărimea de

10 km/h.)

2) Mai multe vehicule se deplasează pe şoseaua orizontală indicată în

figura III.19. Ele au vitezele: vị = 5 m/s spre A, v2 = 18 km/h spre B, v3 = 54

km/h spre A v4 = 20 m/s spre A și vs = 72 km/h spre B.

a) Transformă toate vitezele în m/s.
