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?
