Question

Indiana Jones is trapped in a maze. To find his way out, he walks10 m, then makes a 90o turn and walks 5 m, and then he makesanother 90o turn and walks 7 m.calculate its displacement from initial point

Answer 1

his displacement will be 5.8 m from intial position

Answer 2

Answer: $\sqrt{34}$ m

Explanation:

• We know when we have to measure the displacement of a body we have to measure the shortest distance between its initial position and its final position.
• Here, Miss Indiana Jones in order to make her way out of the maze moves 10 m and then takes a 90° turn and moves 5 m and then again takes a 90° turn and moves 7 m.
• When we represent the graphically we can see that after joining the point of initial position and final position we get a right angle triangle with base 5m and perpendicular 3 m.
• The hypotenuse will be the displacement.
• Displacement=$\sqrt{3^{2}+5^{2} }$

                               = $\sqrt{9+25}$

                               = $\sqrt{34}$ m

• Hence, the displacement will be  $\sqrt{34}$ m.
