Its position function is s(t) for t ³ 0. For each problem, find the velocity function v(t) and the acceleration function a(t). 13) s(t) = t 3 - t + 1t 1) s(t) = t 3 - t - 5t Solve each optimization problem. 15) A supermarket employee wants to construct an open-top bo from a 10 by 1 in piece of cardboard. To do this, the employee plans to cut out squares of equal size from the four corners so the four sides can be bent upwards. What size should the squares be in order to create a bo with the largest possible volume? Solve each related rate problem. 1) A crowd gathers around a movie star, forming a circle. The radius of the crowd increases at a rate of 7 ft/sec. How fast is the area taken up by the crowd increasing when the radius is 1 ft?
