Solve the all parts of given question:
Question: A city bus begins from rest at one bus stop. It accelerates at 0.5 m/s2 for 25 s, travels at a constant velocity for 45 seconds, and then comes to a stop by braking with an acceleration of -0.75 m/s2 until it arrives at the next bus stop.
Part I: What is the distance between the two bus stops?
Part II: What is the average velocity of the bus? Note: The section of road between the two bus stops is straight.)
Don't just give me the answer; explain your steps as well.
The street automobile with the greatest acceleration is the Tempest. It has an acceleration of 6.89m/s2. Suppose the car accelerates from the rest to a final speed of 96.5km/h. How long does it take Tempest to reach this speed.
A very long uniform line of charge has charge per unit length 4.80x10^-6 and lies along the x-axis. A second long uniform line of charge has charge per unit length -2.40*10^-6 and is parallel to the x-axis at y=0.400m.
