It goes up a ramp (increasing its elevation by 1.5 m), and then moves horizontally before striking a spring of force constant k = 100 N/m. The spring is compressed by 5.0 cm as it completely stops the object. 1) How much heat energy was created during this motion? A 5-kg block is dropped from rest from a point 5.0 m above the top of a spring of force constant k = 800 N/m, as shown at right. 2) At what rate is gravity doing work on the block at the instant it strikes the spring?

### What students are saying

• 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.
