5. An object oscillates along a vertical line, and its position in centimeters is given by s(t) = 30(sin(t) 1), where t Z 0 is measured in seconds and y is positive in the upward direction. (a) For which value(s) of t is the velocity zero? (b) Choose one of the values you found in the previous question and nd the equation of the line tangent to 3(t) at that point. (e) Draw a graph of s(t) together with the tangent line you found in the previous part. Label and scale your axes appropriately
