Problem of the Week – 10 A block of steel with mass 2.4 kg sits on a low-friction surface. A bullet of mass 0.04 kg traveling horizontally bounces off the block as shown in the diagram, looking down from above. We take the plane of the motion to be the xy plane (with z pointing outward, toward the viewer). The incident velocity vector of the bullet is <280, 120, 0> m/s and the final velocity

Unformatted text preview: vector of the bullet is <-200, 65, 0> m/s. (a) What is the vector velocity of the block of steel just after the collision? Start from a fundamental principle, and show all your work. (b) What is the increase E thermal in the thermal energy of the block and bullet? Start from a fundamental principle, and show all your work. X Y...
