PLEASE HELP WILL GIVE BRAINLIEST!!!!!!!!

A truck speeds up from a velocity of 6 m/s to 14 m/s in 4 seconds. What is the truck’s acceleration?

Respuesta :

use a = (v1-v2)/t  so u would put 14 (initial velocity or v 1) - 6 (the v2) and divide all of that by 4 seconds to get 2m/s/s as your acceleration

AL2006

Acceleration = (change in speed) / (time for the change)

Change in speed = (ending speed) - (starting speed)

Change in speed = (14 m/s) - (6 m/s)  =  8 m/s

Time for the change =  4 seconds

Acceleration = (8 m/s) / (4 sec)

Acceleration = (8/4) (m/s·s)

Acceleration = 2 m/s²
