A good baseball pitcher can throw a ball at 100 miles/hour (about 45 m/s). If the pitcher were on Sinope, one of Jupiter’s smaller moons, could the pitcher throw the ball fast enough to escape Sinope gravity? Sinope is a roughly spherical with a radious 18000 m and mass of 10x1016 kg.

Using the work energy theorem. what is the velocity of a 850kg car after starting at rest when 13,000j of work is done to it.

Can anybody me with this? ? (picture included.)

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.)
