"A 10ft-long projectile was rapidly accelerated to thousands of miles an hour in a rotating arm before being released for launch 'in less than a millisecond'.
The first suborbital flight used about 20 per cent of the accelerator's full power capacity and reached a test altitude 'in the tens of thousands of feet,' Yaney said.
The vehicle used did not have a rocket engine onboard but SpinLaunch does plan to add one, as well as other internal systems, in future test flights. "

1. How high did it go?
2. How fast was it going when it exited the launcher?
3. How much did the launched object ("lawn dart") weigh?
Q1 is most interesting. Q2 is right behind Q1.
