A case of canned milk weighing 24 ?bs and is released from rest at the top of a plane metal slide which is 30 feet long and inclined of 45º to the horizontal. The air resistance (in pounds) is numerically equal to 1/3 the velocity (in feet per second) and the coefficient of friction on ice is 0.4:

A. Deduce the Differential Equation that models this movement
b. Calculate the velocity of the block at any time "?"
c. Determine the displacement at any time "?"
