If a ball is thrown vertically upward from the roof of a 64 foot building with a velocity of 80 ft/s, it's height after t sexonds is s(t)=64+80t-16t^2. What is the maximum height the ball reaches? What is the velocity of the ball when it hits the ground?
A body is thrown straight up with initial velocity 5 feet per second from a height of 40 feet. After how many seconds will it hit the ground? What will be its maximum height?
You can use calculus or algebra to solve this. Do you know calculus or algebra or both? I don't want to do a problem one way when it should be done another way!!
