Problem 14.71 DroppingAnchor. An iron anchor with mass 35.5 kg and density 7860 kg/m^3 lies on the deck of a small barge that has vertical sides and floats in a freshwater river. The area of the bottom of the barge is 7.80 m^2. The anchor is thrown overboard but is suspended above the bottom of the river by a rope; the mass and volume of the rope are small enough to ignore. Part A After the anchor is overboard and the barge has finally stopped bobbing up and down, has the barge risen or sunk down in the water? By what vertical distance?
Please explain the reasoning and give detailed steps! Thanks!

Challenge Problem: A thin rod of mass M-209 kg and length L-0.782 m is suspended from the ceiling by a frictionless pivot point. A ball of putty with mass m-0.754 kg is thrown at the rod at speed v-2.13 m/s and strikes the rod a distance half way down the rod from the pivot point in a perfectly inelastic collision. The combined the rod+putty then recoils upward upward. By what angle will the system deflect from the vertical after the...
1. The block shown in (Figure 1) has mass m = 7.0 kg and lies on a fixed smooth frictionless plane tilted at an angle θ = 24.5 ∘ to the horizontal. a. Determine the acceleration of the block as it slides down the plane. Express your answer to three significant figures and include the appropriate units. b. If the block starts from rest 19.0 m up the plane from its base, what will be the block's speed when it...
