A 1.2-m long, 2-kg bar rotates on an axle that passes through the center of the bar. There is an air jet at one end of the bar that exerts a force on the bar and rotates it in a CW direction, Starting at rest, the bar reaches an angular velocity of 1000 rad/sec at the end of 4 seconds. a) What is the torque on the bar? b) What is the value of the force F? c) How many revolutions does the bar make in 4 seconds?
