 Joggers Direction |
Example |
|
|
Two joggers, A and B, meet at a street corner and start jogging in different directions. Jogger A goes north at 4 mph and joggers b goes east at 6 mph. After 3 seconds, what is the relative velocity of jogger A with respect to jogger B?
|
||
| Solution |
||
|
|
Location does not matter, relative velocity will be the same at t = 0 or t = 3 secs. vA = vA/B + vB 4j = vA/B + 6i vA/B = -6i + 4j mph |
