A drum of mass 100kg is rolled into the deck of a lorry 1.5m above a horizontal floor using a plank 4m long. Calculate the work done against gravity during the process(g=10m/s^2)?

I need the solve and the answer
work done=force ×distance

W=FD

F=ma

F=100×10=1000N

d=1.5

w=1000N×1.5

w=1,500j

work done=1,500J
Is this correct?
work done=force ×distance

W=FD

F=ma

F=100×10=1000N

d=1.5

w=1000N

=1000N×1.5

=1,500j

Work Done =1,500
6000joule
