While teaching projectile motion last year, I had a particularly bright student who was probably the laziest person I have ever had the pleasure of meeting. One question asked about the motion of a squirrel that had to leap over an electrified fence in order to reach food. The students were asked to solve for one of the variables when given the rest of the variables. His answer was as follows:
“If it was a flying squirrel he wouldn’t have to worry about it”.
