Question

always use significant figure rules. remember that these rules apply to all numbers that are measurements. you hit a golf ball 30.0 m to the south and overshoot the hole. you then hit the ball another 5.0 m back to the north. what is the balls displacement?
30
25
0.0
35

Explanation:

Step1: Definir direcciones

Tomamos el sur como positivo y el norte como negativo.

Step2: Calcular desplazamiento neto

Desplazamiento = 30.0 - 5.0
Desplazamiento = 25.0 m

Answer:

25
