Find the time when the ball hits the ground

WebNov 27, 2016 · 1 A ball is thrown upward from roof of 32 foot building with velocity of 112 ft/sec. The height after t seconds is: s ( t) = 32 + 112 t − 16 t 2. (a) Find the maximum height that the ball reaches. (answer: 228) (b) Find the velocity of the ball when it hits the ground. (answer: − 120.79735) Web32t = 60 (plug the time into original equation (s)) t = 1.875 sec g) When does it hit the ground? You need to find time. If the ball is hitting the ground, that means the height (position) is 0. Use the original equation! s = 60t – 16t2 + 200 2 0 = 60t – 16t + 200 2 0 = -4(4t – 15t – 50) Not factorable! 8 15 32.02 8
