037 CH 19.2 1 of 4> Principle of Impulse and Momentum Constants Part A - Angular velocity of the pulley Learning Goal The pulley shown (Figure 1) has a moment of inertia IA 0.900 kg m2, a radius r 0.300 m, and a mass of 20.0 kg A cylinder is attached to a cord that is wrapped around the pulley. Neglecting bearing friction and the cord's mass express the pulley's final angular velocity in terms of the magnitude of the cord's tension, T (measured in N), 5.00 s after the system is released from rest. Use the principle of angular impulse and momentum. To be able to solve problems involving force velocity, and time by applying the principle of impulse and momentum to rigid bodies moment The principle of impulse and momentum states that the sum of all impulses created by the external forces and moments that act on a rigid body during a time interval is equal to the change in the linear and angular momenta of the body during that time interval In other words, impulse is the change in momentum. The greater the impulse exerted on a body, the greater the body's change in momentum. For example baseball batters swing hard to maximize the impact force and follow through to maximize the impact time Express your answer numerically in radians per second to three significant figures View Available Hint(s) This principle holds true for both linear and angular impulse and momentum. vec For a rigid-body's planar motion, the equations for the linear impulse and momentum in the x-y plane are given by T radians/s t2 Previous Answer Submit X Incorrect; Try Again; 3 attempts remaining Similarly, the equation for the principle of angular Figure 1 of 1 Part B Complete previous part(s) PartC Complete previous part(s) Next > Provide Feedback
