Question

plz do this step by step explanation plz que-3​

Answer 1

Explanation: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=AD

From the figure, using Pythagoras theorem

AD^2=AE^2+ED^2AE=BC=4mC=AB=3m

THEREFORE: ED=6 - EC=3m AD^2 =4^2 +3^2 = 16+9=25

AD =5m

Hence, the displacement of the particle is 5.
