Consider the rotating rod in the figure.
The length of the rod is L m.
While the rod is oriented vertically as shown, the velocity and tangential acceleration of its end point B are given as 1 m/s and -b m/s2, respectively.
Calculate the normal component of the acceleration at point B.
The values of L and b are given below.
b[m/s2] = 3.6;
L[m] = 3;
