A 10-N force is applied to push a block across a friction free surface for a displacement of 5m to the right.

Then I see a diagram that shows Normal force is 20-N and Gravity is 20-N

A) What force(s) is/are doing work on the object?

B) What is the amount of work done by each force?

I know for part of it, the applied force would be
(10N)(5m)(cos) ... So 50J?

And are there any other forces acting? (Gravity, Normal force?)

Here is the problem on my worksheet

Block moves to right. Work is done only direction of motion.
