The vertical displacement y (in cm) of the end of an industrial robot arm for each cycle is y = 2t'- - tan 0.2t, where t is the time (in s). Find its vertical velocity for t = 12s. . . . . . Its vertical velocity for t = 12s is |cm/s. (Round to the nearest tenth as needed.)The electric charge q (in C) passing a given point in a circuit is given by q = tsec 10.4t2 + 2 , where t is the time (in 5). Find the current i (in A) for t = 0.90 s. (i = dq/dt.) i=DA ..... (Do not round until the final answer. Then round to two decimal places as needed.)
