Question

Consider two cylindrical objects of the same mass and radius. Object A is a solid cylinder, whereas object B is a hollow cylinder. Part (a) If these objects roll without slipping down a ramp, which one will reach the bottom of the ramp first? MultipleChoice : 1) There is not enough information to determine 2) Object B 3) They will reach the bottom at the same time. 4) Object A Part (b) How fast, in meters per second, is object A moving at the end of the ramp if it's mass is 340 g, it's radius 31 cm, and the height of the beginning of the ramp is 41 cm? Numeric : A numeric value is expected and not an expression. VA= _____
Part (c) How fast, in meters per second, is object B moving at the end of the ramp if it rolls down the same ramp? Numeric : A numeric value is expected and not an expression. VB= ______

Answer 1

The thing whose moment of inertia is lowest will sink to the bottom first.

What distinguishes a solid from a hollow cylinder?

• All of the mass in the hollow cylinder, ring, or hoop is located r distances from the axis of rotation.
• However, the mass is evenly distributed throughout the solid cylinder.
• This indicates that the solid cylinder's "rotational mass" is less.
• A cylinder is a solid surface created by a line traveling perpendicular to a fixed line, with the end of the line describing a closed figure in a plane.
• When initially at rest, two cylindrical objects with the same mass and radius, one solid and one hollow, roll down the same inclined plane without slipping.

$E=mgh+mv2/2+Iw2/2\\v=rw\\E=mgh+mv2/2+Iv2/2r2\\\\Σmr2$
