Torque required to launch a tennis ball

The tennis ball is put down a pipe and ends up wedged in between 2 wheels (radius = 0.05 m) driven by the two 12 V DC electric motors. The picture below should hopefully clarify the situation: The electric motors are spinning at ~7000 RPM (no load), the motor specs are here: http://www.banebots.com/product/M5-RS555-12.html

Tennis Ball Machine - Tennis ball launcher [the complete guide]

The Prince machines were the first tennis ball launchers available on a large-scale commercial basis and sparked a revolution in the tennis machine industry. These pneumatic machines remained the technology of choice for many years until counter-rotating wheel systems appeared on the market.

Tennis Ball Machine Mosfet control of DC Motors - Project ...

The current system is this. Despite me being in UK the machine basically runs on 110VAC (there is a 220 to 110 transformer).This is rectified to DC to drive the three motors. The motors are 90V, 0.3A, 1/3 HP. One is to drive the oscillation and the ball feed, the other two are to drive the rotating wheels which fire the balls out (really fast!).

assured as one motor can be controlled to rotate faster than one another. The motors used were repurposed from an already existing softball machine, and so were not ideal for soccer ball purposes but still provide a necessary punch. These motors are rated at 90 volts, 3 amps, and 4500 RPM which, through testing, was found to be
