a farmer moves along the boundary of a square field of side 10 m in 40 seconds.what will be the magnitude of displacement of the farmer at the end of 2 minutes 20 seconds from his initial position?

Total distance 40m in 40 sec.
Total time taken by the farmer = 2 min 20 sec. =140 seconds.
Total rounds completed= 140/40=3.5 rounds
That mean...

Change the speed of 6m/s into km/h?

Since we know that,

therefore, 6 m/sec = (6 x 18) / 5 =21.6 km/hr

On a 120 km track, a train travels the first 30 km at a uniform speed of 30 km/h. How fast must the train travel the next 90 km so as to average 60 km/h for the entire trip ?

Speed of the train in the first 30 km, v1 = 30 km/h
Speed of the train in the next 90 km, v2 (to be determined)
Average speed = 60 km/h = (v1 + v2)/2

particle moves 3m north,then 4m east,and finally 6m south.calculate the distance travelled and the displacement?

Distsance=(3+4+6)m = 13m
(Displacement) 2 =3 2+4 2 =9+16 = 25 = (5m) 2
So,Displacement= 5m
