Two 0.50-kg carts are pushed toward each other from starting positions at either end of a 6.0-mlow-friction track. Each cart is pushed with a force of 5.0 N , and that force is exerted for a distance of 1.0 m.
Part A
What is the work done on the two-cart system?
Part B
What is the change in kinetic energy of the system?
Part C
What is the kinetic energy of the center of mass of the system?

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.)
