I'm doing an isaac physics question where i need to state the symbolic equation for the GPE lost from a block sliding down a slope.
I have no number values,
The weight is W,
the angle is alpha (symbol)
the distance on the slope is l
I worked out the horizontal length to be LCos(alpha)

I cant use 9.81 because its a decimal but it tells me that my answer is wrong
(My answer being 10xWxLSin(alpha))
Help?

Gpe lost = k.E. gained. Use suvat to find k.e gained as it goes down the slope by finding its velocity in the end of it.
