Question 12 of 12 Incorrect ncorrect Map sapling leaming A uniform rod is set up so that it can rotate about a perpendicular axis at one of its ends. The length and mass of the rod are 0.811 m and 1.11 kg. What constant-magnitude force acting at the other end of the rod perpendicularly both to the rod and to the axis will accelerate the rod from rest to an angular speed of 6.69 rad/s in 9.79 s Number .20 There is additional feedback available!

Explanation / Answer

angular acceleration(A)=6.69/9.79= 0.683 rads-2

moment of inertia(I)=mL2/3 =1.11*0.8112 /3 =0.243

moment= F.r= I A;

F*0.811=0.243* 0.683

F=0.205 N
