1.	On an open ground , a motorist follows a track that turns to his left by an angle of 60^(@) after every 500 m. Starting from a giventurn , specify the displacement ofof themotorist at thethird , sixth and eighth turn . Compare the magnitude of the displacement with the total path length covered by the motorist in each case.
Answer» Solution :Displacement of magnitude 1 km and direction `60^(@)` with theinitial direction , totalpath length = 1.5km (third turn), NULL displacement VECTOR , path length = 3 km (sixth turn), 866 `m.30^(@)`, 4 km (eight turn)
