please answer it correctly. Thank you and God bless!

The robot arm is elevating and extending simultaneously. At a given instant, 6 = 39,0) = 15 deg/s = constant, l = 0.56 m, i = 0.27 m/s, and 7 = -0.04 m/s2. Compute the magnitudes of the velocity v and acceleration a of the gripped part P. In addition, express v and a in terms of the unit vectors i andj. 0.56 m Answers: V = i m/s a = i m/s2 V = ( i i + i j) m/s a= (i i + i j) m/s2 eTextbook and Media Save for Later Attempts: 0 of 3 used Submit
