Concept explainers
Physics: height of an object. A football player punts a football, which leaves his foot at a height of 3 ft above the ground and with an initial upward of 70ft/sec. the vertical velocity of the football t seconds after it is punted is given by
Where v is in feet per second.
Find the function h that gives the height (in feet) of the football after t seconds.
What are the height and the velocity of the football after 1.5 sec?
After how many seconds does the ball reach its highest point, and how high is the ball at this point?
d. The punt returner catches the football 5 ft above the ground. What is the vertical of the ball immediately before it is caught?
