Question

A cyclist travels a distance of 4km from A to B and then moves a distance of 3km at right angle to AB .Find his resultant displacement.

Solution:-

Given,

• Cyclist travels a distance of 4km from A to B and turns right to AB for 3 km.

resultant^2 = A^2 + B^2

resultant^2 = 4^2 + 3^2

resultant^2 = 16 + 9

resultant^2 = 25

resultant = 5
