What maximum height above the top of the building

Reference no: EM138997

Q1. A rock is throwing from a tall building. The rock reaches its maximum height above the top of the building 1.77 s after being shot. Then, after barely missing the edge of the building as it falls downward, rock strikes the ground 10.0 s after it is launched. In SI units: (a) with what upward velocity is the rock shot, (b) what maximum height above the top of the building is reached by the rock, and (c) how tall is the building?

Q2. John, a 76-year-old grandfather, had been smoking heavily for 26 years and had a persistent cough. A biopsy of his lung tissue revealed considerable amounts of carbon particles. How might this happen considering the natural cleaning mechanism of the respiratory system?
