Caryn purchases an electronic telescope that automatically extends and rotates the lens to focus on incoming meteors in a meteor shower. In this instance, the telescope tube is elevating and
0.2 m, i = -0.3 m/s2. Find the magnitude of the velocity v (in m/s) and acceleration a (in m/s2) of the lens at point 'P'. Also, express v and a in terms of the unit vectors i and j. [Ans. to Check: ||=0.3296m/s]
