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

WebOct 9, 2024 · 3. No, the acceleration of the ball isn't infinite. What happens is that when the ball touches the ground the face in contact with the ground comes to a stop but the rest of the ball above it slows down more gradually, compressing and distorting the ball like a spring. The ball resists being compressed, and when the its centre of mass comes to ... WebOct 27, 2016 · Write down the equations of motion.
