Answer» Given that, r = 12cm = 0.12m 1. Angular speed = 7 revolution in 100s (since, 1 revolution = 2*3.14*r) = 7*(2*3.14*0.12)/(100) = 0.053 rad/s Linear speed, v = Angular speed *radius => v = 0.053*0.12 = 6.3*10^-3m/s =0.63 cm/s 2. Value of acceleration is constant here and always acts towards the center. It is given by a = v^2/r = 0.033 cm/s^2. |
