It’s a cold night in Gotham city. A criminal (of mass 60Kg) is now fleeing on a boat (mass 500Kg) with important research material stolen from UGotham’s Physics Department,. Batman, the caped crusader (mass 100Kg) waits on a bridge until he can jump into the boat. If the velocity of the boat is initially 11 m/s due West and assuming Batman had no horizontal velocity during the jump, what is the velocity of the boat after the superhero’s landing?

A sky diver jumps from a helicopter and is falling straight down at 30 m/s when her parachute opens. From then on, her downward acceleration is approximately = g - cv^2, where g = 9.81 m/s^2 and c is a constant. After an initial "transient" period the descends at a nearly constant velocity of 5 m/s. (a) What is the value of c, and what are its 9 units? (b) What maximum deceleration is the sky diver subjected to? (c)...
