Two thin beams are joined end-to-end as shown in (Figure 1) to make a single object. (The object is seen from the side.) The left beam is 10.9 kg and 1.00 m long and the right one is 42.0 kg and 2.00 m long.​

Atank has a shape of a cone with a radius at the top of 2 m and a height of 5 m. the tank also has a 1 m spout at the top of the tank. the tank is filled with water up to a height of 2 m. find the work needed to pump all the water out the top of the spout. (use 9.8 m/s2 for g and the fact that the density of water is 1000 kg/m3.)
