Consider a football coach pacing back and forth along the sidelines. The diagram below shows several of coach's positions at various times. At each marked position, the coach makes a "U-turn" and moves in the opposite direction. In other words, the coach moves from position A to B to C to D.

1. What is the total distance the coach traveled?
2. What is the total displacement of the coach?

Sagot :

Answer:

distance = 95 yd

displacement = 55 yd

Explanation:

given:

A to B = 35

B to C = 20

C to D = 40

distance = A to B + B to C + C to D

distance = 35 + 20 + 40 = 95 yd.

displacement = A to B - B to C + C to D

displacement = 35 - 20 + 40 = 55 yd.
