During Friday night's storm, power was knocked out to a couple of houses in the grid.  The other homes connected to the grid never lost power.  This is a possible explanation for the power outage.

What is a broken line that connects the two houses to the grid?

During a lacross game, a 0.142 kg lacross ball is shot with a velocity of +31.3 m/s.  The ball is caught by the goalie.  This is the velocity of the ball and head of the goalie's stick immediately after the ball is caught.  Assume the mass of the goalie stick head is 0.370 kg and that the goalie has not applied a force on the stick yet. 

What is 8.68 m/s?

During Saturday's Cubs vs. Giants baseball game, Pete Crow-Armstrong (PCA), hit the first pitch for a home run!  The pitch was thrown with a velocity of -38.4 m/s (84 mph) and left PCA's bat with an exit velocity of +46.0 m/s(103 mph).  This was the acceleration of the baseball.  Assume that the ball was in contact with the bat for 0.7 ms.

What is +121,000 m/s2?
