In 1980, over San Francisco Bay, a large yo-yo was released from a crane. Suppose the yo-yo was 191 kg, and it consisted of two uniform disks of radius 25.7 cm connected by an axle of radius 2.57 cm. What was the magnitude of the acceleration of the yo-yo during (a) its fall and (b) its rise

Henry, whose mass is 95 kg, stands on a bathroom scale in an elevator. the scale reads 830 n for the first 2.4 s after the elevator starts moving, then 930 n for the next 2.4 s. part a what is the elevator's speed 4.8 s after starting? express your answer with the appropriate units.

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.)
