Homework Help: Projectile Question

  1. Sep 15, 2008 #1

    My attempt:

    t=5m/(5m/s)=1s
    using that, calculate how far the block falls in 1s
    x=.5at2+Vt
    =.5(-9.8)(1)(1)+0(1)
    =-4.9m
    thus, the block falls 4.9m


    but I still thinks something not right, any help please

    One second will pass before the object hits the wall, and an object in free fall with no initial downward velocity will fall about 5 m during the first second. So that looks perfectly correct to me. ;)
