**1. Homework Statement**

This problem concerns the mathematical treatment of a simple model

of an electric toy car of mass m, which is initially stationary. The bat-

teries in the car can be considered as an electrical power source with

constant power P.

Find the limiting value of the velocity at very large times and

comment on whether your result seems reasonable.

**2. Homework Equations**

On calculating I got v=sqrt(2Pt/m).

**3. The Attempt at a Solution**

As t -> Infinity, so does v-> Infinity. But that does not makes sense. Where am I wrong. Please help.
