Amailman performed 588j of work lifting a box 1.4 m. how much force did the mailman use?

As we know that work done due a force F is given by formula

here F = applied force due to which work is done

d = displacement of object

now here we will have

W = 588 J

d = 1.4 m

now we can find force by above formula

So applied force by milkman is F = 420 N

the answer is b

explanation:

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper
