You are using a rope to lift a 14.5 kg crate of fruit. Initially you are lifting the crate at 0.500 m/s. You then increase the tension in the rope to 190 N and lift the crate an additional 1.25 m.

a) During this d motion, how much work is done on the crate by the tension force?

b) Find the work done by the force of gravity.

c) Find the work done by the net force?

d) What is the kinetic energy of the crate after being lifted the additional 1.25 m?

e) What is the speed of the crate after being lifted the additional 1.25 m?

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.)
