String is wrapped around the outer rim of a solid uniform cylinder that is free to rotate about a frictionless axle through its center. When the string is pulled with a force P tangent to the rim, it gives the cylinder an angular acceleration a. If the cylinder had thrice the radius, but everything else was the same, the angular acceleration would be O 9a O 3a a/9 O a/3

Suppose the glider and the hanger had equal masses mG = mh . In this situation, do you expect the magnitude of the acceleration of the glider will be: Select all that apply: Greater than g Equal to g Less than g
