Hi, I just had a question i had trouble answering, I am sure its an easy one, but i can't get it, (since I am just starting physics):
a bus starts at rest and accelerates at 1.5m/s^2 until it reaches a velocity of 9m/s. The bus continues at this velocity and then decelerates at -2m/s^2 until it comes to a stop 400m from its starting point. How much time did the bus take to cover the 400m? (ans: 50 seconds)
Im using basic velocity and acceleration formulas and I can't get the answer.
