✅ Verified answer
The particle travels from a to b to c to finally, d. The displacement will be the distance from initial to final points or, from a to d.
Thus, in triangle add by using pythagoras theorem
ad² = 3² +4² = 25
thus, displacement, ad = 5 m
the total distance travelled will be equal to ab + bc + cd = 3m + 4m + 6m
or
distance = 13 m.
And Thanks dear for help in my previous question & hopes that it will help you !!
