**1. The problem statement, all variables and given/known data**

a cars engine produces constant power therefore the cars speed will increase at a constant acceleration.

is this true or false

**2. Relevant equations**

Power=w/t

work=fd

so P=mad/t

**3. The attempt at a solution**

so if p is constant it appears a must be constant. Therefore the statement is true

When I logically think about this situation I think it is false. I imagine myself driving down the highway in my stang turning 2500 rpm at 100 mph. Assume I stay in the same gear. Unless I raise the revs by giving it more gas I will not accelerate. When raising the engine rpm my engine makes more power….so how can I accelerate if my engine maintains a constant rpm(same power output)?
