Answer» tion:The particle starts from A and MOVES northwards to B. It then moves eastwards to C and then southwards to D. Hence, the TOTAL distance covered by the particle is d = AB+BC+CD = 3+4+6 = 13m.Now, displacement is the SHORTEST distance between the INITIAL and the final positions.From the figure, It is clear that the displacement is s=ADFrom the figure, using Pythagoras theoremAD^2=AE^2+ED^2AE=BC=4mC=AB=3mTHEREFORE: ED=6 - EC=3m AD^2 =4^2 +3^2 = 16+9=25 AD =5mHence, the displacement of the particle is 5.HOPE IT HELPS YOU... |
