Calculate the force (in Newtons) required to push a 20kg wagon up a 0.5 radian inclined plane. One Newton (N) is equal to 1https://webwork.math.lsu.edu/webwork...17b12f0d71.png, and the force due to gravity on the wagon is https://webwork.math.lsu.edu/webwork...cce797e421.png, where https://webwork.math.lsu.edu/webwork...ddbff75931.png is the mass of the wagon, and https://webwork.math.lsu.edu/webwork...bac3578ca1.png is the acceleration due to gravity (9.8https://webwork.math.lsu.edu/webwork...b906cfc7f1.png). Please ignore friction in this problem.
Don't think you need calculus for this.
As you push the wagon up the incline, the component of gravity parallel to the incline ( ) is what counteracts the force you're providing. So, the force you provide must be equal to this (in which case the wagon would be moving at a constant velocity) or greater (in which there will be a net force accelerating the wagon upward).
I'm inputting [20(9.8)sin(0.5)] into the program accepting my answers and it is claiming it incorrect. Am I doing something wrong?
Edit: The program is at fault, thanks for the help!
