POTENTIAL ENERGY AND ENERGY CONSERVATION 7 7.1. IDENTIFY: U grav = mgy so ΔU grav = mg ( y2 − y1 ) SET UP: + y is upward. EXECUTE: (a) ΔU = (75 kg)(9.80 m/s 2 )(2400 m − 1500 m) = +6.6 × 105 J (b) ΔU = (75 kg)(9.80 m/s2 )(1350 m − 2400 m) = −7.7 × 105 J EVALUATE: U grav increases when the altitude of the object increases. 7.2. IDENTIFY: The change in height of a jumper causes a change in their potential energy. SET UP: Use ΔU grav = mg ( yf − yi ). EXECUTE: ΔU grav = (72 kg)(9.80 m/s2

Adultery Hurts No one commits adultery without first being able to justify their behaviour to themselves. The problem with such justifications is they are falsehoods‚ a way of engaging in bad behaviour without having to think about the consequences of the adultery to self and others.
