Which of the following is true for displacement?

(a) It cannot be zero.

(b) Its magnitude is greater than the distance travelled by the object.

(a) It cannot be zero.

(b) Its magnitude is greater than the distance travelled by the object.

As we know displacement is the shortest distance between the initial and final positions

(a) is not true. Displacement can be zero.

The body may be at rest, there...

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 ?

Answer.

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...
