1) A tank is full of water. Find the work W required to pump the water out of the spout. (Use 9.8 m/s² for g. Use 1000 kg/m³ as the weight density of water. Assume that a = 4 m, b = 4 m, c = 12 m,and d = 1 m.)
W = ___ J

I got 5017600 then in scientific notation it would be 5.0176 X 10^6, then in Juls in would be 5.02?

I got the answer wrong an would like to know how you do this problem?

2. Suppose that 5 J of work is needed to stretch a spring from its natural length of 32 cm to a length of 44 cm.

(a) How much work is needed to stretch the spring from 40 cm to 42 cm? (Round your answer to two decimal places.)
1.25 J

(b) How far beyond its natural length will a force of 40 N keep the spring stretched? (Round your answer one decimal place.)
? cm

for B I got 11.52, did I do something wrong?

A small water pump is used for an irrigation project. The pump takes water in from a river at 10oC, 100 kPa at a mass flow rate of 16.83 kg/s. The exit line enters a pipe that goes up to an elevation 26.15 mm above the pump and river, where the water runs into an open channel. Assume the process is adiabatic and that the water stays at 10 oC. Find the required pump work.
