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 , v x - t , and v y - t graphs for the motion.

A man throws a football with an initial upward velocity component of 15.0 m/s and a horizontal velocity component of 25.0 m/s. Air resistance may be ignored. 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 being 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 it travelled horizontally during this time?
A quarterback throws a football with an initial velocity of 25 m/s at an angle of 40 degrees above the horizontal. Calculate the following:
a) The maximum height the football reaches above its starting point.b) The time it takes for the football to reach its maximum height.c) The horizontal distance the football travels before it hits the ground.d) The total time the football is in the air.
(Note: Assume that air resistance is negligible, and use a standard acceleration due to gravity of 9.8 m/s².)
A rookie quarterback throws a football with an initial upward velocity component
of 12 m/s and a horizontal velocity component of 20 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 travelled horizontally
during this time?
The ball will reach its highest point
at t = 1.22 s, with the highest point
at 7.35 m above its initial position.
The football will return to its original
O level at t = 3.66 s, which is thrice
that of time it took for the football
to reach its highest point. At this
time, it will cover a horizontal
distance of 73.2 m.
