Find the distance traveled by the block

[DeanBH]

Homework Statement

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

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? =)
