Question

Your house is at x = 4.2 m and you are initially at x = -2.4 m. You walk 1.2 meters in the negative x direction to go into a shop. How far away is the shop from your house?

Answer 1

Answer:

7.8 METRE

IF THE HOUSE IS AT X = 4.2 M

INITIAL POSITION X=-2.4 M

AFTER WALKING 1.2 M IN NEGATIVE X DIRECTION X'= -2.4-1.2=-3.6 M

DISTANCE FROM SHOP TO HOUSE IS 3.6 +4.2

= 7.8 METRE
