Example 1 A 0.98 kg block slides on a frictionless horizontal surface with speed 1.32m/s.  The block encounters an  unstretched spring with force constant 245N/m, as shown.  a)  how far is the spring compressed before the block comes to rest? b)  how long is the block in contact with the spring before it comes to rest? c)  how far is the spring compressed when the kinetic energy of the block is equal to the potential energy stored  in the spring?

    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.
