A child pulls a friend in a little red wagon with constant speed.? - red wagon invitations
If the child pulls with a force of 16 N of 10.4 m, and the handle of the car is at an angle of 28 degrees above the horizontal, oblique, like the work of the child in the car?

This equation is W = Fd cos Theta-Theta where the degree is given where it is, and F is given the power d is the distance traveled. It tells us that F = 16 N, D = 10.4 m, and theta = 28, then plug the equation for W or solve work.
W = Fd cos theta
W = (16) (10.4) (COS 28)
W = 146.92 J
