2. A hockey puck is sliding along a horizontal line with a positive position being movement to the right. The position 3 of the puck, in feet, from the origin at time t 2 0, in seconds, is given by the function: 5(t) = 6 cos(t) 6t + 4 (a) (3 points) Determine the velocity function, v(t), for this object. v(t) = (b) (4 points) At What time t is the velocity function is rst equal to 0 on the interval [0, 27f]? Include units in your answer. Show all supporting work. t = (c) (5 points) Shiloh determines that that v(2) ~ -0.54. Interpret this statement in the context of the given situation by selecting the correct choice in each set of brackets and filling in the blanks with correct units to complete the sentence below: O Position When the O Rate is 2 O Time O Up O Position O Down the object is moving at a O Rate of 0.54 O Left O Time O Right
