Suppose that two objects attract each other with a gravitational force of 10 Newtons. If the distance between
the objects doubled, what would the new force of attraction
between them be? (include the magnitude and units in your
answer).

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.
