A17,250 kg rocket is pushed with a thrust of 6,450,284 n. what is the acceleration of the rocket?

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.

Amaterial that provides resistance to the flow of electric current is called a(an) (1 points)
