Test 1 Study Problems Displacement vs. Distance A jogger runs along the sides of an equilateral triangle as seen below from point A through point B to point C, where each side is 100 m. 1. How far has he run? (Distance) 200 m 2. What is his displacement? 100 m + Velocity vs. Speed The jogger above completed his run from point A to point C (going through point B) in 20 s. 3. What is his speed? 4. What is his velocity for that run? 5. What would his velocity be if he completed the triangle by running back to point A? Acceleration A car speeds up from rest to 30 m/s in 6 seconds travelling in the positive x-direction. 6. What is its change in velocity? 7. What is its acceleration? Later on the same car slams on its brakes, coming to a stop from its speed of 30 m/s in only 3 seconds. 8. What is its change in velocity? 9. What is its acceleration? Weight Determine the weight of the following masses: 10. 10 kg 11. 50 kg 12. 100 kg 13. 275 kg A B C

    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.
