Would a 12v electric motor have enough torque?

I'm designing an automatic ball launcher for my dog. I'm toying with the idea of attaching a shaft on an electric motor. The shaft will spin and hit the ball, hopefully far enough to make this fun for the dog. Would a 12 volt, 200 rpm motor be strong enough? Too fast? I was going to power it with rechargeable AA batteries or something of the like. The shaft will probably be made of aluminum and about 12" long.

Thanks for the help.

Update:

My original idea was to use a car window motor (gear motor) to crank the shaft to a certain point and then a spring would snap it back to hit the ball.

    No, with low power AA batteries the task can not be done.

    You need to carry a car battery and starter motor, and that would not be fun for you and the dog !

    You need to specify the torque the 12 volt motor is capable of supplying. Most cheap hobby motors that work from AA batteries have low torque, maybe 20 oz-in. Which won't work to launch a ball. There are 12 volt motors that will work, but they take many amps of power that the AA batteries can't provide.

    get the motor out of a golf cart. or use the motor out of an electric scooter. they have automobiles for mounting on a conventional bicycle that would desire to paintings too. the electrical powered fan automobiles might take diverse paintings to make it paintings off of batteries and doubtless would not make the appropriate sort of potential to flow a flow kart.
