Homework Statement



A child holds a sled on a frictionless, snow-covered hill, inclined at an angle of 25 degrees.If the sled weighs 56 N, find the force exerted on the rope by the child.

Homework Equations


[itex]\Sigma[/itex]F=ma


The Attempt at a Solution


I set up a right triangle with 56N as the hypotenuse. I then figured the x component of force, or the force exerted on the rope by the child, to be 56sin25. I got 23.67N but when I submitted this it was wrong am I missing something here.

That answer looks right to me.
The method is not. The 56 N acts straight down, and 56*sin(25) is the component acting downward along the hill. An equal force upward along the hill is needed to cancel it.
