I want to make a Twinkie splat when I throw it off a building. Because Twinkies are notoriously hard to crush, I want it to hit the ground moving at 128ft/s. I am going to throw it straight down, with a speed of 8ft/s off the roof of the building. How high does the building need to be

Answer:


s=253.6524712 \approx 253.7

Step-by-step explanation:

From the question we are told that

Initial speed
v=8ft/s

Final speed
v=128ft/s

Generally the Newtons equation of motion is mathematically represented by


V_f^2-V_0^2=2as

with

Therefore


a=g=>9.81m/s^2\\a=32.17ft/s^2

Therefore


128^2-8^2=2*(32.17)*s


16320=2*(32.17)*s


s=(16320)/(2*(32.17))


s=253.6524712 \approx 253.7
