c) When will the bottle hit the ground? d) Determine the impact velocity of the bottle. 13. During a fireworks Reasoning and Proving display, a starburst Representing Selecting Tools rocket is shot upward Problem Solving with an initial velocity Connecting Reflecting of 34.5 m/s from a Communicating platform 3.2 m high. The height, h, in metres, of the rocket after t seconds can be modelled by the function h(t) = -4.9+2 + 34.5t + 3.2. a) Determine the velocity and acceleration of the rocket at 3 s. b) When the rocket reaches its maximum height, it explodes to create a starburst display. How long does it take for the rocket to reach its maximum height? () At what height does the starburst display occur ? d) Sometimes the rockets malfunction and do not explode. How long would it take for an unexploded rocket to return to the ground? e) At what velocity would it hit the ground? 14. Consider the motion of a truck that is braking
