Why Isn't the Normal Force on the Sled 250 N?

[123lar]

Homework Statement

The question is: An empty sled of mass 25 kg slides down a hill with constant speed of 2.4 m/s. The slope of the hill is inclined at an angle of 15 degrees

How come the normal force of the sled is NOT 250 N?

Homework Equations

Assuming here g= 10 N/kg, the weight is 250N.

However since the mass is moving down an incline at 15 degrees, the normal force will be a component of the weight i.e. a fraction of the weight.
