Cars collision

Use arrows to represent exerted forces

Use comparable measurement units to forces (e.g. cm)

Replace the image with an abstract figure showing cars as arrows with headings

The more the force the more the length of the arrow

Hock arrows end-to-end but keep length and direction

Draw an arrow from the tail of the long arrow to the head of the short arrow

measure the length of the new arrow and multiply by value of lb = 1 cm

(1) Use arrows to represent exerted forces

(2) Use comparable measurement units to forces (e.g. cm)

(3) Replace the image with an abstract figure showing cars as arrows with headings

(4) The more the force the more the length of the arrow

(5) Hock arrows end-to-end but keep length and direction

(6) Draw an arrow from the tail of the long arrow to the head of the short arrow

(7) measure the length of the new arrow and multiply by value of lb = 1 cm

Since 1 cm = 40 lb, and the net arrow = 5.5 cm, then the net force = 220 lb
