The figure applies to the next questions. There is a body segment with up to three forces applied: proximal, distal, and external. In the coordinate system shown, the acceleration is [1, O, 0] m/s2, and the angular acceleration is 1 rad/s2 about the z axis. The mass is 1 kg, and the moment of inertia is 1 kg-m2. The proximal force is [0, 1, 0] N, and the proximal moment is 0 N-m. The grid has equal spacing 1 cm. 1 cm proximal COM distal If inverse dynamics is performed in the proximal-to-distal direction and, what is the reaction force exerted by this body segment on the distal body segment?

Find the acceleration of the specified object. (Hint: Recall that if a variable is changing at a constant rate, its acceleration is zero.) A boat is pulled into a dock by means of a winch 2 meters above the deck of the boat (see figure). The winch pulls in rope at a rate of 1.7 meters per second. Find the acceleration (in m/sec?) of the boat when there is a total of 5.2 meters of rope out. (Round your answer to three decimal places.) m/sec2 Not drawn to scale Submit Answer
