Answer: the smallest initial velocity that is required to throw the stone is 56 ft/s

Step-by-step explanation:

We know that;

u = initial velocity  

v = final velocity  = 0

a = acceleration  = -g = -32,

s = distance travelled  = 49 feet

V² - u² = 2aS

we substitute

0² - u² = 2 × -32 × 49

0 - u² = -3136

u² = 3136

u = √3136

u = 56 ft/s

Therefore the smallest initial velocity that is required to throw the stone is 56 ft/s
