2) 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 extending 0.5m, L = 0.2 , L = deg at the same time. At a given instant, Ⓒ = 45°, 0 = 10 = constant, L = S -0.3 m/s². a. Find the magnitude of the velocity v (in m/s) of the lens at point 'P'. [Ans. to Check: |v| = 0.3296 b. C. Find the acceleration a (in m/s²) of the lens at point 'P'. [Ans. to Check: |a| = 0.357] Express v and a in terms of the unit vectors i and j (cartesian coordinates).
