with an initial velocity having an x-component of 20 m/s and a y-component of -10 m/s. The particle experiences an acceleration in the x-direction, given A particle moves in the xy-plane, starting from the origin at t - by a, - 4.0 m/s (a) Determine the total velocity vector at any time. SOLUTION Conceptualize The components of the initial velocity tell us that the particle starts by moving toward the ---Select- . The x-component of velocity starts at 20 m/s and increases by 4.0 m/s every second. The y-component of velocity never changes from its initial value of -10 m/s. We sketch a motion diagram of the situation in the figure. Because the particle is accelerating in the +x-direction, its velocity component in this direction increases and the path curves as shown in the diagram. Notice that the spacing between successive images increases as time goes on because the speed is ---Select-- C. The placement of the acceleration and velocity vectors in the figure helps us further conceptualize the situation. Categorize

    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.
