In the automated welding setup shown, the position of the two welding tips G and H is controlled by the hydraulic cylinder D and rod BC. The cylinder is bolted to the vertical plate which at the instant shown rotates counterclockwise about A with a constant angular velocity of 1.6 rad/s. Knowing that at the same instant the length EF of the welding assembly is increasing at the constant rate of 300 mm/s, determine

(a) The velocity of tip H,

(b) The acceleration of ti pH.
