In this problem, assume that the effect of friction can be discounted. (Remember to include the unit in the answer.) T 20 cm If, in the above diagram, no gravitational force slowed the ball's movement (that is, if the right-hand side of the diagram were horizontal), how far would the ball travel? 10,000 cm,100,000 cm, or indefinite distance

Write the equation for momentum, first using symbols for the variables, then using words for the variables.

Arock collection comes from which part of earth?

Aperson stands on a platform, initially at rest, that can rotate freely without friction. the moment of inertia of the person plus the platform is ip. the person holds a spinning bicycle wheel with its axis horizontal. the wheel has moment of inertia iw and angular velocity ωw. take the ωw direction counterclockwise when viewed from above. part a what will be the angular velocity ωp of the platform if the person moves the axis of the wheel so that it points vertically upward?
