(a) An insect moves with a speed of $31.3~m/s$ (b) The angular speed is $31.3~rad/s$
(a) We can find an insect's speed: $a_c = \frac{v^2}{r}$ $v = \sqrt{a_c~r}$ $v = \sqrt{(980~m/s^2)(1.0~m)}$ $v = 31.3~m/s$ An insect moves with a speed of $31.3~m/s$ (b) We can find the angular speed: $\omega = \frac{v}{r}$ $\omega = \frac{31.3~m/s}{1.0~m}$ $\omega = 31.3~rad/s$ The angular speed is $31.3~rad/s$
