Conceptual Physics Acceleration and Velocity II Velocity (How fast) Distance (How far) Acceleration Free Fall V=gt D= ½gt² linear V=at D= ½at² 1. Suppose a car moving in a straight line steadily increases its speed each second, first from 35 to 40 km/h, then from 40 to 45 km/h, then from 45 to 50 km/h. What is its acceleration? 2. In 5 seconds a car moving in a straight line increases its speed from 50 km/h to 65 km/h, while a truck goes from rest to 15 km/h in a straight line. Which undergoes greater acceleration? 3. Joel driving a jumbo jet taxiing down the runway, receives word that it must return to the gate to pick up an important passenger who was late to his connecting flight. The jet is traveling at 45 m/s when the pilot receives the message. What is the acceleration of the plane if it takes the pilot 5 s to bring the plane to a halt? 4. Alana is walking to the hairdresser’s at 1.3 m/s when she glances at her watch and realizes that she is going to be late for her appointment. Alana gradually quickens her pace

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
