Given two vectors A = 4.00i + 7.00j and B = 5.00i -2.00j a. Find the magnitude of each vector.
b. Find the vector difference C= A – B, give its magnitude and direction.
c. Draw the vector A, B and C.
d. Find the scalar product of A. B
e. Find the vector product D= A x B, draw D and give its magnitude.

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.)
