A toy sled with a mass of 1.0 kg is sliding down a ramp that makes an angle of 25į with the
ground. The coefficient of kinetic friction between the toy sled and the ramp is 0.25.

4. In a coordinate system where the x-axis is parallel to the ramp and the y-axis is perpendicular to
the ramp, what are the components of the toy sledís weight?
5. In a coordinate system where the x-axis is parallel to the ground and the y-axis is perpendicular to
the ground, what are the componentís of the toy sledís weight?
