Solving Work Done in Pushing Sled Up Snowy Incline

[foxproff]

Homework Statement

A father pushes horizontally on his daughter’s sled to move it up a snowy incline, If the sled moves up the hill with a constant velocity, how much work is done by the father in moving it from the bottom to the top of the hill? (angle of incline is 15 degrees
F + f(k) + mg = 0
F= -f(k)-mg
= -(-66.2N) - (-88.7N)
= 66.2N + 88.7N
= 154.9N

Work, w=fd
=154.9N * 13.9m
2153J

Homework Equations

work = force,f * Distance, d

The Attempt at a Solution

F + f(k) + mg = 0
F= -f(k)-mg
= -(-66.2N) - (-88.7N)
= 66.2N + 88.7N
= 154.9N

Work, w=fd
=154.9N * 13.9m
2153J

Is that the entire question?

yes
the plane makes an angle of 15 degrees with the horizontal
it has a height of 3.6m from the ground
