Aball is thrown vertically upward from the ground with velocity ~v0. assume air resistance exerts a force proportional to the velocity. write down a differential equation for the position. rewrite this equation in terms of the velocity and solve for ~v(t). does your solution give the correct result for t → [infinity]? what is the physical meaning of this asymptotic value? would you expect the time during which the ball rises to be longer or shorter than the time during which it falls back to the ground?

The temperature at a point (x, y) is t(x, y), measured in degrees celsius. a bug crawls so that its position after t seconds is given by x = 6 + t , y = 8 + 1 3 t, where x and y are measured in centimeters. the temperature function satisfies tx(3, 9) = 5 and ty(3, 9) = 4. how fast is the temperature rising on the bug's path after 3 seconds? (round your answer to two decimal places.)
