### Physics Problem - What is the Average Power Output of an Engine?

What
is the average power output of an engine when a car of mass

*accelerates uniformly (***M***=const) from rest to a final speed***a***over a distance***V***on flat, level ground? Ignore energy lost due to friction and air resistance. Derive a formula for average power***d****P***in terms of variables: the mass***ₐ***, the final speed***M***, and the distance***V***.***d**

PP

*=***ₐ****P***(***ₐ***,***M***,***V***) ?***d**
Solution:

*=*

**Pₐ**

**W***/*

**t***-*

**K***=*

**Kₒ**

**W***=0*

**Kₒ***=½*

**K***²*

**MV***=½*

**Pₐ***²*

**MV***/*

**t***=*

**V**

**at***½*

**d=***²= ½*

**at**

**Vt***=2*

**t***/*

**d**

**V***=½*

**Pₐ***²*

**MV***/*
