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

$1350 J$
first multiply $90 \cdot 10 = 900 N$ this is the force .then put the formula $W = F \cdot d$ 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.
