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

Abearing is designed to a reduce friction b. support a load c.guide moving parts such as wheels, shafts and pivots d. all of the above

This problem has been solved! see the answera non-uniform fire escape ladder is 6.0m long whenextended to the icy alley below. it is held at the top by africtionless pivot, and there is neglibible frictional force fromthe icy surface at the bottom. the ladder weighs 250n, and it'scenter of gravity is 2.0m along the ladder from the bottom. amother and child of total weight 750n are on the ladder 1.5m fromthe pivot. the ladder makes an angle θ with the horizontal.find the magnitude and direction ofa) the force exerted by the icy alley on the ladderb) the force exerted by the ladder on the pivotc) do your answers in part a and b depend on the angle?

According to newtons universal law of gravitation, which would change the parh of the ball so it traces out widest curved path possible?
