Work backwards, because you cannot solve it forwards since there are two unknowns. (a) Start with the energy transferred to the compressed spring. The block transfers energy to the spring, that's why it compresses. Ek = Ee mv^2 = kx^2 (halves cancel) v = sqrt[(kx^2)/m] v = ....

Christina's answer doesn't take into account that you'll be paid interest on the interest. After the first year, you'll have $11,000 in your account -- $10,000 + 1,000. The second year: 11,000 x .1 = 1,100 11,000 + 1,100 = 12,100 The third year: 12,100 x .1 = 1,210 12,100 + 1,...

OK on the 0.077. That is a very good reason why the answer may have been a little low but I still would say that some of the iron may have been lost in the transfer from the crucible. For the five volumetric solutions, I assume the prof gave you the solutions to use. I would ...
