A car is moving 14.4 m/s. It decelerates at -1.55 m/s2 for 4.26 s. It then accelerates at
1.83 m/s2 until it reaches 11.8 m/s.
What was the total time?
(Unit = s)

10 points! will mark brainiest! in a heat engine if 1,000 j of heat enters the system and the piston does 500 j of work, what is the final internal energy of the system if the initial energy was 2,000 j 1: write the equation 2: list out your known variables 3: plug the numbers into the equations 4: solve 5: write your solution statement that includes initial energy and final energy added you so much!
