ANSWER ANY OF THEM AND ILL BE GRATEFUL THANK YOU !!!!!!!Arnold and Jeremy are working on a rocket project for math class. Their job is to find the time it takes for a model rocket to reach its maximum height and how long it will take the rocket to return to Earth if the rocket’s parachute fails to deploy. They are making calculations for three different rocket engines and each engine has a different initial velocity. They are a bit confused on how to make the calculations. Take a look at the information that they were given and show them how to set up the equations and solve for the times requested. ````````````````````````````````````````````````````````````````````````` 1. A model rocket is launched from the ground with an initial velocity of 160 ft/sec. a. How long will it take the rocket to reach its maximum height? Show all work in the space provided. ````````````````````````````````````````````````````````````````````````````` b. Assume the model rocket’s parachute failed to deploy and the rocket fell back to the ground. How long would it take the rocket to return to Earth from the time it was launched? Show all work in the space provided. ```````````````````````````````````````````````````````````````````````````````````` 2. A model rocket is launched from the ground with an initial velocity of 288 ft/sec. c. How long will it take the rocket to reach its maximum height? Show all work in the space provided. `````````````````````````````````````````````````````````````````````````````````` d. Assume the model rocket’s parachute failed to deploy and the rocket fell back to the ground. How long would it take the rocket to return to Earth from the time it was launched? Show all work in the space provided. ````````````````````````````````````````````````````````````````````````````````````` 3. A model rocket is launched from the ground with an initial velocity of 352 ft/sec. `````````````````````````````````````````````````````````````````````````````````````e. How long will it take the rocket to reach its maximum height? Show all work in the space provided. `````````````````````````````````````````````````````````````````````````````````````f.
