Question

How much work does it take to lift a `90 kg` weight `3/2 m`?

Answer 1

`1350J`

Explanation:

first multiply `90*10=900N` this is the force .then put the formula `W=F*d` then multiply this force with the distance which is `1.5` and you will get the answer. 90Kg is the mass to so you have to convert it into Newtons by multiplying it with 10 which is the gravitational force.
