Calculate the speed of an 8.0*10^4kg airliner with a kinetic energy of 1.1*10^9j.
Answers: 2
![E_{k}=\frac{1}{2}*m*v^{2}\\ where:\\m = mass = 80000[kg]\\v = velocity [m/s]\\E_{k}= kinetic energy [J]=1100000000[J]\\Replacing:\\v=\sqrt{\frac{2*E_{k} }{m} } \\v=\sqrt{\frac{2*1100000000 }{80000} }\\v=165.83[m/s]](/tpl/images/0448/9235/caf95.png)
