- In the figure here, a stationary block explodes into two pieces L and R that slide across a frictionless floor and then into regions with friction, where they stop. Piece L, with a mass of 3.3 kg, encounters a coefficient of kinetic friction HL = 0.52 and slides to a stop in distance di = 0.32 m. Piece R encounters a coefficient of kinetic friction µR = 0.49 and slides to a stop in distance dr = 0.49 m.

- Prof. P's dwarf lime tree is doing well this year and provides those lime slices for his refreshing online lecture glass of water. One of those limes with a mass of 45.2 grams falls vertically from the tree at a height of 1.3 meters and elastically bounces straight up off the greenhouse floor. If that poor lime was in contact with the floor for 0.11 seconds, what was the force on the lime from the floor in Newtons? (assume up is positive) Prof. P. has experimentally determined (because he does that sort of stuff) that a 5N force will bruise a lime and make it nasty for his drink - is this lime OK?Leah is competing in the national diving championships.
