Answer:ω = 100000rev/min * 2πrad/rev * 1min/60s = 10 500 rad/s
t = 2 min = 120 s
(a) ω = ωo + at
10500 rad/s = 0rad/s + α*120s
α = 87.3 rad/s²
(b) a_t = αr = 87.3rad/s² * 0.095m = 8.29 m/s²
(c) a_r = ω²r = (10500rad/s)² * 0.095m = 1.04e7 m/s²
which is 1.04e7 / 9.8 = 1.06e6 "g"s
(a little over 1 million "g"s)
