Figure Q2 shows a robot arm that can elevate and extend simultaneously. At a given instant, the robot arm has a constant angular velocity of 10%/s, 1 = 0.6 m, i = 0.3 m/s, and ī= -0.6 m/s².

a. Evaluate the velocity and acceleration of the gripped part P in radial and transverse directions.

b. Assess the influence of angle on the velocity of the gripped part P in x and y directions.
