Answer:
Work performed=57.14 NM
Power= 22.86 J/s
Step-by-step explanation:
Work done= Force/distance
W=F/d
we don't have the force but weight and force is the same thing so to find weight we have to use the formula
Weight= mass × gravitational field strength
W=mg
W= 10.0×10. (please remember that g has a constant value of 10)
W=100 N
Therefore the force is 100 N
Going back to the original equation
W= 100/1.75
W= 57.14 NM
Power=Work done/time
P= W/t
P= 57.14/2.5
P= 22.86 J/s
