Sure.....but
keep in mind that it will take a while to spin up a wheel to 1750 RPM, so by the time it speeds up you may only have a second or two to shoot all the balls. Total time to shoot 10 balls is not 1 second, but 1 second plus the time to speed up the wheel (perhaps almost 10 seconds depending on how you design your system)
Yes, if you just let a wheel go at the full speed of the large CIM it may provide too much velocity, but it depends on the wheel diameter (well, actually the radius really).
My calculations (which I will not post here) show that you have to be a bit careful with the diameter and inertia. However, there will be plenty of energy in the wheel to fire off a bunch of balls (remember, its not just the motor power that is shooting the balls, but mostly the energy already stored in the wheel which is really a flywheel). Its almost a given that you will have plenty of energy to shoot all the balls when your wheel is up to adequate speed to give you the velocity that you want.
You might want to consider gearing for the wheel as well - my calculations show a real benefit to this (but you will have to figure out just what it is). I will leave it to you to do the energy, inertia, speed, and power calculations.
Dont forget that the velocity of the balls will be slightly different as well since as the wheel slows down with each shot, the subsequent shots will be a bit slower,which means that the range will make a difference as to how many balls you can actually get into the goal when shooting them that fast.
