Question

An object in a simulation accelerates from rest to a speed of 4 meters per second in 2 seconds. It then accelerates linearly for the next 3 seconds until it reaches 10 meters per second. The object remains at that speed (acceleration = 0) for 3 seconds and then de-accelerates linearly until it comes to rest 2 seconds later. Which graph demonstrates the speed of the object for those 10 seconds?

Answer 1

Most likely D

Explanation:

Answer 2

since you did not give the choices for which graph it represent, i will just describe what will it look like. for time 0 - 2 s , it will go diagonally upward until it reach at 4 m/s in the y axis. then from 2 - 5 sit will go diagonally upward until it reach at 10 m/s in the y axis. then from 5 - 8 s will be horizontal. then it will go diagonally downwards
