Compute all parts of given question:
Question: A rookie quarterback throws a football with an initial upward velocity component of 16.5m/s and a horizontal velocity component of 18.1m/s. Ignore air resistance.
Part A: How much time is required for the football to reach the highest point of the trajectory?
Part B: How high is this point?
Part C: How much time (after it is thrown) is required for the football to return to its original level?
Part D: How does this compare with the time calculated in part (a)?
Part E: How far has it traveled horizontally during this time?
I need help to find how much time is required for the football and express your answer using three significant figures.
