The position function s(t). in metres, of the ball above the ground is s(t) -5+ + 30t + 1 , where ti is in seconds. 3) Determine the maximum height reached by the ball. bj Determine the velocity of the ball when it is caught 1 m above the ground. 3) An object is moving horizontally. The object's displacement, s, in metres at t seconds is described by the function s(t) = 4t - 7+ + 2t- 3) Determine the velocity and acceleration at t = 2 seconds. b) When is the object stationary? Describe the motion immediately before and after these times. c) At what time, to the nearest tenth of a second, is the acceleration equal to 0? Describe the motion at this time. 4. Determine the first and second derivative of the following functions. a) h(x) = 3x4 - 4x - 31' - 5 b) f(x) = (21 -5)3 c) y = It! 15
