Page 2 of 6 PHYS-114 Test #1 Summer 2006 [1] (10 pts) A car driving South slows down slightly as it approaches a curve in the road ahead. The car rounds the curve at constant speed and then speeds up slightly as it heads off East. Draw a complete motion diagram for the car as seen by a helicopter hovering overhead. Show graphically how you obtain at least two of your acceleration vectors. [2] (10 pts) The grid below shows two vectors. (a) In the grid provided graphically determine the resultant vector r R = r A + 2 r B . (b) Express the resultant vector R in unit vector notation. (c) Then determine the magnitude of your resultant vector R and its angle with respect to the positive x-axis.

    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.
