all questions pls

The position function of an object is given by s(t) = =3 - 25t, where time, t, is in seconds, distance, s, is in metres, and ( 2 0. What is the acceleration at the instant the object is momentarily at rest? n. Sm/s b. -9.8m/s c. 10m/s2 d. 2m/s2 Mark: 3 The height function of a tossed baseball is given by h(t) - -4.912 + 14.71 + 2, where time: t is in seconds, height: h, is in metres, and t is greater than or equal to 0. What is the maximum height, to the nearest metre, reached by the baseball? a. 13m b. 14m c. 20m d. 10m Mark: 3 This question requires a full and complete solution.
