Question

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.:)

​

Answer 1

• V_A=30m/s
• V_B=40m/s

As both are moving in same direction

`\\ \bullet\sf\longmapsto R_(AB)=R_A+R_B`

`\\ \bullet\sf\longmapsto R_(AB)=30+40`

`\\ \bullet\sf\longmapsto R_(AB)=70m/s`

• time=4min=240s

`\\ \bullet\sf\longmapsto R_s=R_(AB)* t`

`\\ \bullet\sf\longmapsto R_s=70(240)`

`\\ \bullet\sf\longmapsto R_s=16800m`
