. A stone is dropped from the top of a building that is 500m high. Disregarding air resistance how long does it take the stone to reach the ground?

  • Physics -

    Use kinematics equation:

    Δx = vi(t) + (1/2)at²
    vi=0
    g=-9.8
    -500=(1/2)(-9.8)t²
    t=√(2(-500)/(-9.8))
    =10.1 s (approximately)
