Homework Help: Find the distance traveled by the block

  1. Apr 17, 2008 #1
    1. The problem statement, all variables and given/known data
    A smooth plane is inclined at 73.74 Degrees to the horizontal a block of mass 5kg is on the slope.

    its 73.47 degrees inclined
    5kg mass
    g = 9.8

    Find the distance traveled by the block in 0.8 Seconds



    3. The attempt at a solution

    i can't quite remember how i find this out.

    mgsinX works down the plane
    mgcosX works in the direction of graity

    its smooth = no friction. i can't remember how i balance the equation to work out acceleration and things that i can put it into an equation of motion to find time

    gSinX = A = 9.4

    s = ut + 1/2AT^"

    s = 0*0.8 + 1/2 * 9.4 * 0.8^2

    = 3.008 metres..

    right? =)
