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?

- The kinetic energy E of an object varies jointly with the object’s mass m and the square of the object’s velocity v . An object with a mass of 50 kilograms traveling at 16 meters per second has a kinetic energy of 6400 joules. What is the kinetic energy of an object with a mass of 70 kilograms traveling at 20 meters per second?arrow_forwardA Skydiver When a skydiver jumps from an airplane, his downward velocity, in feet per second, before he opens his parachute, is given by v=1761-0.834t, where t is the number of seconds that have elapsed since he jumped from the airplane. What is the velocity after 5 seconds?arrow_forwardIf you travel 300 miles on the first day and then drive v miles per hour for t hours on the second day, then the total distance traveled over the teo-day period is given by d=300+vt miles. Use a formula to express v as a function of d and t for this two-day event.arrow_forward
