The spring elongates an amount L . If pulled a little further and then released, the mass oscillates with a measured period T . No other information is recorded. 1) Using only this information, derive an equation for the gravitational acceleration, g . When a 50-gram mass is attached to a certain spring, is oscillates with a

A simple pendulum has a mass of 400 grams and a length of 1.30 meters. It is pulled to right a distance of 10 cm and then released from rest at time t = 0. 3) What is its frequency of oscillation? 4) What is the maximum speed of the pendulum bob? 5) What is the instantaneous acceleration of the pendulum bob at time t = 20 s?...

    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.
