Q. If the bullet has a mass of 21.5 and a speed of 310 , how high will the block rise into the air after the bullet becomes embedded in it?

Q. Four particles with masses m1 = 19 kg, m2 = 29 kg, m3 = 2 kg, and m4 = 39 kg sit on a very light (massless) metal sheet and are arranged. Find the moment of inertia of this system with the pivot at the following point. (Assume the rotation axis is parallel to the z direction, perpendicular to the plane of the drawing)
