## Question:

The ball B has mass M and is attached to the end of a rod whose mass may be neglected. If the rod is subjected to a torque M = ${ at }^{ 2 }$ + bt + c, determine the speed of the ball when t = ${ t }_{ 1 }$ . The ball has a speed v = ${ v }_{ 0 }$ when t = 0. Given: M = 10 kg , a = 3 N⋅m/${ s }^{ 2 }$ , b = 5 N⋅m/s , c = 2 N⋅m , ${ t }_{ 1 }$= 2 s , ${ v }_{ 0 }$ = 2 m/s , L = 1.5 m
