A ride in an amusement park consists of a rotating arm AB that has an angular acceleration of aAB = 1 rad>s2 when vAB = 2 rad>s at the instant shown. Also at this instant the car mounted at the end of the arm has an angular acceleration of A = {0.6k} rad>s2 and angular velocity of V = {0.5k} rad>s, measured relative to the arm. Determine the velocity and acceleration of the passenger C at this instant.

If the slider block C is fixed to the disk that has a constant counterclockwise angular velocity of 4 rad>s, determine the angular velocity and angular acceleration of the slotted arm AB at the instant shown.

At the instant shown, car A travels with a speed of 25 m>s, which is decreasing at a constant rate of 2 m>s2, while car C travels with a speed of 15 m>s, which is increasing at a constant rate of 3 m>s. Determine the velocity and acceleration of car A with respect to car C.

At the instant shown, car B travels with a speed of 15 m>s, which is increasing at a constant rate of 2 m>s2, while car C travels with a speed of 15 m>s, which is increasing at a constant rate of 3 m>s2. Determine the velocity and acceleration of car B with respect to car C.

The two-link mechanism serves to amplify angular motion. Link AB has a pin at B which is confined to move within the slot of link CD. If at the instant shown, AB (input) has an angular velocity of vAB = 2.5 rad>s, determine the angular velocity of CD (output) at this instant.

The disk rotates with the angular motion shown. Determine the angular velocity and angular acceleration of the slotted link AC at this instant. The peg at B is fixed to the disk.

The Geneva mechanism is used in a packaging system to convert constant angular motion into intermittent angular motion. The star wheel A makes one sixth of a revolution for each full revolution of the driving wheel B and the attached guide C. To do this, pin P, which is attached to B, slides into one of the radial slots of A, thereby turning wheel A, and then exits the slot. If B has a constant angular velocity of vB = 4 rad>s, determine VA and AA of wheel A at the instant shown.
