If the block at C is moving downward at 4 ft/s, determine the angular velocity of bar AB at the instant shown.

The sphere starts from rest at = 0 and rotates with an angular acceleration of
= (4
) rad/s2, where
is measured in radians. Determine the magnitudes of the velocity and acceleration of point P on the sphere at the instant
= 6 rad.

Due to an engine failure, the missile is rotating at = 3 rad/s, while its mass center G is moving upward at 200 ft/s. Determine the magnitude of the velocity of its nose B at this instant.

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.

At the instant shown, gear A is rotating with a constant angular velocity of A = 6 rad/s. Determine the largest angular velocity of gear B and the maximum speed of point C.
