Expert Answer
Given that,
Velocity while moving along east, u = 20 m/s
Distance covered in 5 sec (East), d = 20× 5 = 100 m
Velocity while moving along west, v = ?
Now, the distance travelled before the vehicle comes to rest after 15 seconds (5 sec towards east and rest 10 sec towards west) is:
d’ = 10 × v = 100
∴ v = 10 m/s along West
