Planar Kinematics of a Rigid Body (PKRB)
14.

Arm ABCD is printed at B and undergoes reciprocating motion such that = (0.3 sin 4t) rad, where t is measured in seconds and the argument for the sine is in radiaus. Determine the largest speed of point A during the motion and the magnitude of the acceleration of point D at this instant.

vAmax = 0.0600 m/s, aD = 1.002 m/s2
vAmax = 0.300 m/s, aD = 0.960 m/s2
vAmax = 0.0600 m/s, aD = 0.916 m/s2
vAmax = 0.300 m/s, aD = 0.288 m/s2
