How much work does it take to raise a #19 kg # weight #15 m #?

Answer 1

#2793J#

Work is the vector dot product of the applied force and the displacement moved in the direction of the force. #W=vec F * vecx#.
The lifting force overcomes the downward weight force of the object and is given by #f=mg=19xx9.8=186.2N#

Assuming it is lifted directly upwards in a straight line, the force acts in the direction of the displacement, and hence the work done is

#W=186,2*15=2793J#

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
