If an object is projected upward with an initial velocity of 64 ft per sec from a height of 80 ft, then its height in feet t seconds after it is projected is a function defined by f(t)=−16t2+64t+80. How long after it is projected, will it hit the ground?
a ball is thrown vertically upward from the ground and a studentlooking out the window sees it moving past him at 5m/sec. thestudent's eyes are 10m above grounda. what maximum hieght does the ball reach?b. how long does it take to go from a height of 10m to its heighestpointc. find its velocity and acceleration 0.5 sec after it leaves theground
