Answer a and b

Name: (1) A stone was thrown vertically upwards from a balcony that is 32 feet above the ground with the initial velocity of 16 ft/sec. Assume that the height h(t) of the stone at time t (in seconds) follows the general position of a free-falling object h(t) = -16t2 + vet tho where vo is the initial velocity and ho is the initial height. [10pts] (a) When does the stone hit the ground? [5pts] (b) What is the velocity of the stone when it hits the ground? [5pts]
