Question 3 of 24 The position of an object moving horizontally after t seconds is given by the function s = 751 -t', for t - 0, where's is measured in feet, with s = 0 corresponding to positions right of the origin. a. When is the object stationary, moving to the right, and moving to the left? b. Determine the velocity and acceleration of the object at t = 1. c. Determine the acceleration of the object when its velocity is zero d. On what intervals is the speed decreasing? a. The object is stationary att = my (Simplify your answer. Use a comma to separate answers as needed.) The object is moving to the right on . Simplify your answer. Type your answer in interval notation. Use a comma to separate answers as needed. The object is moving to the left on. Simplify your answer. Type your answer in interval notation. Use a comma to separate answers as needed.) b. The velocity of the object at t = 1 is Simplify your answer.) The acceleration of the object at t= 1 is"] (Simplify your answer.) c. The acceleration of the object when its velocity is zero is Simplify your answer.) d. The speed is decreasing on the interval(s) . Simplify your answer. Type your answer in interval notation.
