A laboratory centrifuge rotates @ 4000 rpm…what is the magnitude of acceleration (phys 1111)

A typical laboratory centrifuge rotates at 4000 rpm. Testtubes have to be placed into a centrifuge very carefully because ofthe very large accelerationsWhat is the acceleration at the end of a testtube that is 10 cm from the axis of rotation?Express your answer using twosignificant figures. i got1.8×104m/s2 whichis right….and my question is this one….For comparison, what is themagnitude of the acceleration a test tube would experience ifdropped from a height of 1.0 m and stopped in a 1.0-ms-longencounterwith a hard floor?Express your answerusing two significant figures.
