The net forward force on the propeller of a 3200 g model airplane is 7.0 N. What is the acceleration of the airplane?
0.46 m/s^2
2.2 m/s^2
0.0022 m/s^2
22000 m/s^2

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.)
