Vedclass · Answer

(D) The speed of the thief's jeep is $v_t = 9 \, m/s$.The speed of the policeman's motorcycle is $v_p = 10 \, m/s$.The relative speed of the policeman with respect to the thief is $v_{rel} = v_p - v_t = 10 - 9 = 1 \, m/s$.The initial distance (separation) between them is $d = 100 \, m$.To catch the thief,the policeman must cover this relative distance at the relative speed.Time taken $t = \frac{d}{v_{rel}} = \frac{100 \, m}{1 \, m/s} = 100 \, s$.Therefore,it will take $100 \, seconds$ for the policeman to catch the thief.
