The, displacement of the body will be, , 57. Read the following and answer the, questions from (i) to (v)., The distance travelled by a moving body is, the actual length of the path covered by it,, irrespective of the direction in which the, body travels. It is scalar quantity. Its SI unit, is metre. e.g. consider the motion of an, object moving along 4 straight path. :, Speed of an object is defined as the distance, , travelled by it per unit time., , S F _ Distances), peed of an object (v)= inet), , Speed is a scalar quantity: The SI unit of, , speed is metre per S€ (m/s). ae, , distance travelled by is either, , positive or zero, SO the spe!, , positive or zero bi, , 67, , Distance tr:, u ‘avelled b «, by iti ate A, Time £, Tie Distance (j, iia ee, , Osan a, 10:30 am, , 25, , 10:40 am. ae, EES eB, 11:00 am. i, , 11:00 sen Oa, , 115 am i, , 11:30 am. 50, , @) Which of the followin,, ; ig graph co, ih, given data?, , ‘D (km), Din), , : ar, oO t@) 0, , D (km) D(km),, , @), , O t@) 0 t@), (ii) At which time the train js travelling at, its highest speed?, {a)10:00- 10:30, , (p)10:30-10:40, 0
