STEM Lessons for College Students

3.12 . A rookie quarterback throws a football with an initial upward velocity component of 12.0 m>s and a horizontal velocity component of 20.0 m>s. Ignore air resistance. (a) How much time is required for the football to reach the highest point of the trajectory? (b) How high is this point? (c) How much time (after it is thrown) is required for the football to return to its original level? How does this compare with the time calculated in part (a)? (d) How far has the football traveled horizontally during this time? (e) Draw x-t y-t vx@t and vy@t graphs for the motion.

I have not created a lesson for this question yet.

Please leave a comment below with specifics about the question, and I will make a detailed lesson on it as soon as possible. (I can usually have something up within a day.)

NEED IMMEDIATE HELP? Get the student solution manual here: University Physics Manual otherwise, I should be able to get a video lesson up within a day or so.
