Calculating Potential Energy on a 1.9° Incline

[xmflea]

In a lab we set up an air track and gave it a 1.9 degree incline. we then slid a glider down the track. the glider passed through two photogates, which calculated two velicities.
the glider weighed .190kg
the first velocity V1 was 0.524m/s
the second velocity V2 was 1.06m/s
h=3.6cm

Now i am supposed to calculate potential energy PE1 which is given by the equation
PE1=mgh,
is was wonder if i did this right, i did PE1=0.190x9.8x3.6
if not, what is the approach?

the equation is basically correct. Check the units - (height)
