    a: after 1 seconds it will have fallen 0.2452

    after 2 seconds it will have fallen 0.981

    after 3 seconds it will have fallen 2.2072

    after 4 seconds it will have fallen 3.924

    Explanation:

    the formula for acceleration due to gravity is (ignoring friction I think)

    g = G*M/R^2

    earths gravitational constant is about 9.807

    g = 9.807*M/R^2

    The average weight of a brick is 5 pounds and I'm going to say it's 10 feet off the ground.

    g = 9.807*5/10^2. g = 0.4905 so every second the brick will go 0.4905 fps faster. (fps means feet per second.)

    after 1 seconds it will have fallen 0.2452

    after 2 seconds it will have fallen 0.981

    after 3 seconds it will have fallen 2.2072

    after 4 seconds it will have fallen 3.924
