Problem 1UHart Mechatronics students have developed a robotic armprogrammed to an angular position in polar coordinates with therelationship = (2/à) sin(πt), where and t are expressed inradians and seconds, respectively. Simultaneously, the arm is pro-grammed to extend so that the distance to A follows the relationshipr = 4 + 3e-1.4t, where r and t are expressed in feet and seconds,respectively. When t = 2.65 s,Determine:(a) the velocity of point A in polar coordinates (êr and êŋ),(b) the velocity of point A in rectangular coordinates, (î and ĵ)(setup and use a transformation matrix)(c) the acceleration of point A in polar coordinates (ê, and êŋ)(d) the acceleration of point A rectangular coordinates (î and ĵ)

Solution:- Given; θ=2πsin(πT) r=3(2+2e-1.5t) ,t=2.25
