Over 75 seconds a truck traveled at a constant velocity of 25 meters per second to the west. Find the trucks displacement

1875 m west

Explanation:

Take east to be the positive direction.  Given:

v₀ = -25 m/s

a = 0 m/s² (constant velocity)

t = 75 s

Find: Δx

Δx = v₀ t + ½ at²

Δx = (-25 m/s) (75 s) + ½ (0 m/s²) (75 s)²

Δx = -1875 m

diagram is missing, but i will try to explain your doubt.

answer:

amplitude is the maximum displacement or distance moved on a point of a vibrating body or wave measured from its equilibrium position.it is equal to half the length of vibration path.

1 - wave length

2 - amplitude

3 - crest

4 - trough

explanation:

duh.
