Question

A photographer wants to take a picture of a particularly interesting flower, but he is not sure how far away to place his camera. He takes three steps forward, four back, seven forward, then five back. Finally, he takes the photo. As measured in steps, what was his displacement? Assume the forward direction is positive

Answer 1

Answer:1 unit forward

Step-by-step explanation:

Given

Photographer wants to take a picture so he take three step forward i.e. +3 units , four back i.e.-4 units , Seven steps forward i.e. +7 units,

Finally 5 steps backward i.e. -5 units

therefore its net displacement is

=+3-4+7-= +1 unit

That his displacement is 1 unit forward
