An Olympic skier moving at 20.0 m/s down a 30.0o slope encounters a region of wet snow, of coefficient of friction μk = 0.740. How far down the slope does she go before stopping?

a.119 m
b.145 m
c.170 m
d.199 m

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.)
