The angular speed of a propeller on a boat increases with constant acceleration from 11 rad/s to 26 rad/s in 2.4 seconds. Through what angle did the propeller turn during this time?

Answer 1

Vo t + (1/2) a t^2

a = change in speed/change in time = (26-11)/2.4 = 6.25 rad/sec^2

so
11* 2.4 + (1/2) *6.25 * 2.4^2
