m1= mass 1 = 1.1 kg
Vi1 = initial velocity 1 = 2.7 m/s
m2= 2.4 kg
V2i = -1.9 m/s
We assume east as positive and west as negative.
Apply the formulas:
Vf1 = ?
![vf1=(\frac{m1-m2}{m1+m2})Vi1+(\frac{2m2}{m1+m2})Vi2](https://tex.z-dn.net/?f=vf1%3D%28%5Cfrac%7Bm1-m2%7D%7Bm1%2Bm2%7D%29Vi1%2B%28%5Cfrac%7B2m2%7D%7Bm1%2Bm2%7D%29Vi2)
Replacing:
![Vf1=\frac{(1.1-2.4)}{(1.1+2.4)}2.7+\frac{(2\times2.4)}{(1.1+2.4)}-1.9](https://tex.z-dn.net/?f=Vf1%3D%5Cfrac%7B%281.1-2.4%29%7D%7B%281.1%2B2.4%29%7D2.7%2B%5Cfrac%7B%282%5Ctimes2.4%29%7D%7B%281.1%2B2.4%29%7D-1.9)
![Vf1=(\frac{-1.3}{3.5})2.7+(\frac{4.8}{3.5})-1.9](https://tex.z-dn.net/?f=Vf1%3D%28%5Cfrac%7B-1.3%7D%7B3.5%7D%292.7%2B%28%5Cfrac%7B4.8%7D%7B3.5%7D%29-1.9)
![Vf1=-1-2.6=-3.6\text{ m/s}](https://tex.z-dn.net/?f=Vf1%3D-1-2.6%3D-3.6%5Ctext%7B%20m%2Fs%7D)
Answer: 3.6 m/s west
I would say that it would take her 35 * 2 cashing Bill properly because I multiply 0.25 times 16 which gave me 1.50 + 2.50 equals 3.50
Answer:
Explanation:
In a conductor, electric current can flow freely, in an insulator it cannot.
Metals such as copper typify conductors, while most non-metallic solids are said to be good insulators, having extremely high resistance to the flow of charge through them.
Most atoms hold on to their electrons tightly and are insulators.
The answer is 17 m because you have to add the 15 m and the 8 m together to get the answer so it will be like this 17x17 = 15x15 + 8x8 got it?
