2.50: a) From Eq. (2.15), the velocity v 2 at time t + = t t dt αt v v 1 1 2 ) ( 2 2 1 2 1 t t v - + = α 2 2 1 1 2 2 t t v α α + - = = (5.0 s m ) – (0.6 3 s m )(1.0 s) 2 + (0.6 3 s m ) t 2 = (4.40 s m ) + (0.6 3 s m ) t 2 . At t 2 = 2.0 s, the velocity is v 2 = (4.40 s m ) + (0.6 3 s m )(2.0 s) 2 = 6.80 m/s, or 6.8 s m to two significant figures. b) From Eq. (2.16), the position x 2 as a function of time is dt v x x x t t 1 1 2 + = dt t t t ) ) s / m

    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.
