Let s(t) = 1 - 5 sint where s represents the position (displacement), at time t, of an object moving on a straight line, where t is measured in seconds. Consider such an object over the time interval 0, . Determine the position of the object at t = 0 and t = The object's position at t = 0 is feet The object's position at t = . is feet Determine the average rate of change of the object over the time interval 0, = ]- The object's average rate of change over 0, is: ft/sec Determine the instantaneous rate of change (velocity), speed, and acceleration of the object at t= The object's velocity at t = is ft/sec The object's speed at t = is ft/sec The object's acceleration at t = - 4 is ft/sec? At what time over 0, " , if any, did the object change directions? If multiple solutions exist, enter the solutions using a comma-separated list. O The object changed directions at I = O The object did not change directions over (0, ]
