A solid disk is released from rest and rolls without slipping down an inclined plane that makes an angle of 25.0° with the horizontal. What is the speed of the disk after it has rolled 3.00 m, measured along the plane?

  • Physics -

    change of GPE= lateral speed+ rotational speed

    mg3/sin25= 1/2 mv^2+ 1/2 I w^2

    but w=vr, then solve for v. Look up I for a solid disk.
