Jennifer is a Civil Engineer at a construction site building the launch pad for NASA/Boeing's Space Launch System (SLS), the rocket that will send astronauts to Mars and is the most powerful rocket ever made! Antonio is one of the Aerospace Engineers that designed the SLS, and is sent to the construction site to make sure Jennifer's launch pad can handle it. Jennifer is standing next to a heavy wrecking ball, which carries a 850 C charge, when Antonio walks by making fun of her design to the other Aerospace Engineers he is with. The Civil Engineers at the site look at Jennifer, demanding that she does something about Antonio. When Antonio is 10 m away from the wrecking ball, Jennifer takes a small 0.2 kg bolt that carries a 110 C charge, holds it at a point between Antonio and the ball (at a distance 0.5 m away from the center of the ball), and releases it. How fast is the bolt going when it strikes the back of Antonio's helmet? (Antonio has a kevlar helmet and is safe.)
