1.	When a motor cyclist takes a U-turn in 4s what is the average angular velocity of the motor cyclist ?
Answer» SOLUTION :When the motor cyclist TAKES a U-turn, ANGULAR displacement, `theta = pi` RAD and t = 4s. The AVERAGE angular velocity, `omega = (theta)/(t) = (pi)/(4) = 7.855 xx 10^(-1) = 0.7855 " rad s"^(-1)`.
