Hello. Be v grateful any assistance with this.

Question is energy to haul 2000kg 4 metres up a 1 in 100 incline with 300 Newtons friction

Answer is given as exactly 1.98 kJ.

The only figures I can see that relate to anything here are 2000kg minus 10 = 1980, and 1:100 is 0.01 which times 1000 is ten. I don't see how you put those together.

Many thanks :)
