Two buses 'A' and 'B' are moving in the same direction with the velocities 30m/s and 40m/s respectively. Find the relative velocity of the bus 'A' with respect to the bus 'B'. Calculate the relative displacement between them after 4 minutes.:)
​

Respuesta :

  • V_A=30m/s
  • V_B=40m/s

As both are moving in same direction

[tex]\\ \bullet\sf\longmapsto R_{AB}=R_A+R_B[/tex]

[tex]\\ \bullet\sf\longmapsto R_{AB}=30+40[/tex]

[tex]\\ \bullet\sf\longmapsto R_{AB}=70m/s[/tex]

  • time=4min=240s

[tex]\\ \bullet\sf\longmapsto R_s=R_{AB}\times t[/tex]

[tex]\\ \bullet\sf\longmapsto R_s=70(240)[/tex]

[tex]\\ \bullet\sf\longmapsto R_s=16800m[/tex]
