A Solid Sphere Of Uniform Density Starts From Rest And Rolls Without Slipping A Distance Of Da 2 8 M Down Aq 36 Incline 1 (27.48 KiB) Viewed 33 times

A solid sphere of uniform density starts from rest and rolls without slipping a distance of da 2.8 m down aq=36" incline. The sphere has a mass M4.5 kg and a radius R0.28 m a) Of the total kinetic energy of the sphere, what fraction is translational? KEKE 0.714 Reset Enter 0714 OK DIL HELP: When an object rolls without slipping, there is a relationship between the linear velocity of the CM and the angular velocity. HELP: The total KE is KE(trans)+ KEco) b) What is the translational kinetic energy of the sphere when it reaches the bottom of the incline? KE-80 Help Reset Enter 0.80 NO c) What is the translational speed of the sphere as it reaches the bottom of the ramp? m/s Help Resel Enter v=5.116 5.118 NO Now let's change the problem a little. d) Suppose now that there is no frictional force between the sphere and the incline. Now, what is the translational kinetic energy of the sphere at the bottom of the incline? KE 13 Help Exter
