A worker pushes a wheelbarrow up a slope with a force of 100 pounds. The slope has an angle of 21° with the horizontal. Express the force vector F in terms of i and j, where i is the force vector of magnitude 1 pound pointing along the hoizontal component of the worker's direction, and j is the vector of magnitude 1 pound pointing upwards.

so, F=?

please draw a figure.and show i , j axis

There is no figure...that is why I am confused

by slope, does it mean like inclined plane? Like this?|dw:1337428449487:dw|
