Homework Statement
A crane lifts a 2.25x10^3 bucket containing 1.15m^3 of soil (density = 2.00x10^3kg/m^3) to a height of 7.50 m. Calculate the work the crane performs.
Homework Equations
D=m/V
W=Fd
The Attempt at a Solution
F=2n25x10^3N
d=7.50m
D=2.00x10^3 kg/m^3
V=1.15m^3
W=?
alright so I've calculated the mass the object will have and i got 2.3 x 10^3kg
Now i was just wondering if anyone could help me on where to go from here?
