What is the momentum of Fred if he weighs 3000kg and is traveling with a velocity of 20 m/s west?

What is the average speed of a car that travels 40 mph for 1 hour and 60 mph in another hour?

Amira pulls a 3 pound wagon 4 feet. how much work has she done?

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.)
