Highschool physics problems

  1. Apr 9, 2012 #1
    1. a ball rolls of off the edge of a table top 1m high and strikes the floor at a point 15m horizontally away from the edge of the table. find (a) the time of flight (b) the initial velocity and (c)

    2. a boy throws a ball upward into an improvised basketball ring at an angle of 60° from the horizontal and leaves the boy's hands at the height of 1.22m from the ground. the ring is 3.2m high and 5m horizontally away from the point where the boy was standing. what should be the initial velocity of the ball when it leaves boy's hands so it will go into basket?

    Where's your attempt at the solution?

    Write out the equations you think you will need.
    Write out the constants and variables:

    Initial velocity (u) = ?
    Time of flight (t) = ?
    Distances (s[itex]_{x}[/itex]) = 15m
