Part A - Practice Problem: I direction with speed 2.9 m/s. Find the position of the center of mass at this instant. Now let's apply the center-of-mass equations to a simple one-dimensional system. Suppose a 2.0 kg cat and a 3.0 kg dog are moving toward each other along the I axis, heading for a fight. At a particular instant, the cat is 1.0 m to the right of the origin and is moving in the + 1 direction with...

Pleas help me with both parts I don't know how to do this. Thank u Constants A 530.0 -g bird is flying horizontally at 2.40 m/s, not paying much attention, when it suddenly flies into a stationary vertical bar, hitting it 25.0 cm below the top (the figure (Figure 1)). The bar is uniform, 0.800 m long, has a mass of 2.20 kg , and is hinged at its base. The collision stuns the bird so that it just drops...
