Atourist being chased by an angry bear is running in a straight line toward his car at a speed of 3.9 m/s. the car is a distance d away. the bear is 23 m behind the tourist and running at 6.0 m/s. the tourist reaches the car safely. what is the maximum possible value for d?

Light from the sun reaches the earth in 8.3 minutes. the velocity is 3.00 x 10^8 m/s. how far is earth from the sun? i know how to get to d = (3 x 10^8 m/s)(498 sec). i just don't know how to get from there to the answer being 1.5 x 10^11 m.

In what direction does an applied force move an object

The bar of prob. 5/82 is repeated here. the ends of the 0.4-m bar remain in contact with their re- spective support surfaces. end b has a velocity of 0.5 m/s and an acceleration of 0.3 m/s2 in the di- rections shown. determine the angular accelera- tion of the bar and the acceleration of end a.
