Extracted text: Part B - Finding the time needed to reach a specific speed (3.75t +2.55) N-m, where t is in If the shaft is 0.200 m long, the ball has a speed of v = 2.90 m/s when t = 0, and the rod is subjected to a torque M seconds, determine the time it will take for the ball to reach a speed of 8.00 m/s. Express your answer to three significant figures.


Extracted text: Learning Goal: To apply the principle of angular impulse and momentum to find final speed and the time to reach a given speed. M B As shown, ball B, having a mass of 10.0 kg, is attached to the end of a rod whose mass can be neglected. Part A - Finding the final speed of the ball If the rod is 0.550 m long and subjected to a torque M = (2.45t² + 4.45) N-m, where t is in seconds, determine the speed of the ball when t= 3.10 s. The ball has a speed of v = 2.80 m/s when t = 0. Express your answer to three significant figures and include the appropriate units.
