Two objects, A and B, have the same size and shape and mass. Object A lands on a foam cushion while object B lands on concrete. Both objects will have the same impulse, but object A will have a
collision time and a
force of impact.

A. Smaller: smaller
B. Bigger; smaller
C. Bigger; bigger
D. Smaller; bigger

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.)
