Question

Un corp parcurge distanta de 100 metri in 10 secunde, iar alt Corp in 30 de secunde, calculati diferenta dintre viteza lor.

Answer 1

v1 = d/t1 = 100m/10s = 10m/s

v2 = d/t2 = 100m/30s = 10m/3s = 3, (3) m/s

v1 - v2 = 10m/s - 3,(3)m/s

= 10m/1s - 10m/3s

= 30m/3s - 10m/3s

= 20m/3s

= 6,(6) m/s
