13.65: a) 2 m m Splits at 2 so , energy, kinetic all is energy where 0 2 2 1 E E mv E x = = k stays same k E A kA E 2 so 2 2 1 = = Then 2 means 2 A A E E 2 means 2 so 2 T T m m k m π T = b) 2 m m Splits at A x = where all the energy is potential energy in the spring, so E doesn’t change. A kA E so 2 2 1 = stays the same. , 2 so 2 T T k m π T = as in part (a). c) In example 13.5, the mass increased. This means that

Unformatted text preview: T increases rather than decreases. When the mass is added at , = x the energy and amplitude change. When the mass is added at , A x ± = the energy and amplitude remain the same. This is the same as in this problem....

### 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.

• 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.
