- Calculate The Potential Kinetic And Mechanical Energies Of The Sphere In Front As Functions Of Time Important A Roll 1 (69.54 KiB) Viewed 34 times
I really just need to know what formulas I need or how exactlyto solve it!
Thank you!
Calculate the potential, kinetic, and mechanical energies of the sphere in front as functions of time. Important: a rolling solid sphere not only has translational kinetic energy (0.5m²); it also has rotational kinetic energy equal to 0.2m2. Therefore, the (total) kinetic energy of a rolling solid sphere is 0.7mv². Make graphs of the potential, kinetic, and mechanical energies the sphere as functions of time. What is the (total) kinetic energy K of the sphere in front on the lowest part of the track? K=

Kinetic and Potential Energy In this lab, two solid spheres are released from rest at the same time and from the same height. At the far-right end of the track, the tracks are at the same level. • The frame rate (number of frames per second) is shown in the remote control. • The physical width of the space captured by the video is 1.5 m. The video is 1280 pixels wide. • Each sphere has a mass of 85 g.
