angular impulse

To apply the principle of angular impulse and momentum to find final speed and the time to reach a given speed.

 

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 0.400 m long and subjected to a torque M=(2.50t2+3.25) N?m, where t is in seconds, determine the speed of the ball when t=2.30 s. The ball has a speed of v=1.90 m/s when t=0.

 

Express your answer to three significant figures and include the appropriate units.

 

Part B - Finding the time needed to reach a specific speed

 

If the shaft is 0.250 m long, the ball has a speed of v=4.10 m/s when t=0, and the rod is subjected to a torque M=(4.00t+1.05) N?m, where t is in seconds, determine the time it will take for the ball to reach a speed of5.50 m/s.

 

Express your answer to three significant figures.
