Homework Statement
A 310-kg feraligatr slides 3.0m down a 30∘incline at Rainbow Valley and is kept from accelerating by his trainer who is pushing on the feraligatr's back parallel to the incline.
Express all your answers using two significant figures.
a Howw much force does the trainer exert?
How much work does the trainer do on her feraligatr?
What is the work done by the force of gravity?
What is the net work done on the feraligatr if friction is ignored?
Express your answer using two significant figures.

The Attempt at a Solution
well i did net force for the first part which resulted me into drawing a fbd and I got Applied force which is the trainer minus feraligator which becomes applied force - mgsin30 which got me 1500N which i initially got wrong because of the calculator
second part i did
1500*d which is 4600 N (f=fd)
which then got me confused on part c which i don't understand what does it mean force of gravity
i don't know how net work works and friction wasnt given in the first place
