Homework Help: physics

Posted by cyndi on Monday, January 29, 2007 at 4:18pm.

A 10.0-kg cylinder rolls without slipping on a rough surface. At the instant its center of amss has a speed of 10m/s, determine (a) the translational kinetic of its center of mass (b) the rotational kinetic energy about its center of mass and (c) its total kinetic energy.

can u check if this is the correct answer?

a) KE=.5Mv^2
KE=.5(10)(10)^2
KE=500J

B) KE=.25Mv^2
KE=.25(10)(10)^2
KE=250J

C) 250J+500J=750J

please tell me if that is correct ornot XD thanks

^please check that work i have shown above thanks
