A 5.0 kg rod with a length of 2.8 m has an axis of rotation atits center. Looking at the rod with its axis perpendicular to thispage, a force of 14.5 N at 68o is applied to the rod 1.1m from the axis of rotation. This torque would angularly acceleratethe rod in a counter-clockwise direction. Assume that the torquecontinues to be applied during the motion consider in this problemand that there are no other torques. Consider the counter-clockwisedirection to be positive. At to = 0.00 s, the angularvelocity of the rod is 3.6 rad/s. Avoid round-off error in thelater answers. Unless directed otherwise, keep four significantdigits.
Calculate Rotational Inertia and net torque that acts upon therod.
What is the angular acceleration? Calculate your answer usingthe four-digit results from the questions above.
What is ωo equal to in this problem? Input only twodigits.
Calculate ω, when t = 5.6 s. Use the four-digit result forangular acceleration when calculating, but input the answer withonly two significant digits.
What is Δθ, when t = 7.9 s? Use the four-digit result forangular acceleration when calculating, but input the answer withonly two significant digits using scientific “E†notation. Forexample, 560 would be entered as 5.6E2.  Â
