Answer:
The value is ![v = 2.3359 *10^{4} \ m/s](https://tex.z-dn.net/?f=v%20%20%3D%20%202.3359%20%2A10%5E%7B4%7D%20%5C%20m%2Fs)
Explanation:
From the question we are told that
The initial speed is ![u = 2.05 *10^{4} \ m/s](https://tex.z-dn.net/?f=u%20%3D%20%202.05%20%2A10%5E%7B4%7D%20%5C%20%20m%2Fs)
Generally the total energy possessed by the space probe when on earth is mathematically represented as
![T__{E}} = KE__{i}} + KE__{e}}](https://tex.z-dn.net/?f=T__%7BE%7D%7D%20%3D%20%20KE__%7Bi%7D%7D%20%2B%20%20KE__%7Be%7D%7D)
Here
is the kinetic energy of the space probe due to its initial speed which is mathematically represented as
=>
=> ![KE_i = 2.101 *10^{8} \ \ m \ \ J](https://tex.z-dn.net/?f=KE_i%20%3D%20%202.101%20%2A10%5E%7B8%7D%20%5C%20%5C%20m%20%5C%20%5C%20J)
And
is the kinetic energy that the space probe requires to escape the Earth's gravitational pull , this is mathematically represented as
![KE_e = \frac{1}{2} * m * v_e^2](https://tex.z-dn.net/?f=KE_e%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20%20%2A%20%20m%20%2A%20%20v_e%5E2)
Here
is the escape velocity from earth which has a value ![v_e = 11.2 *10^{3} \ m/s](https://tex.z-dn.net/?f=v_e%20%3D%20%2011.2%20%2A10%5E%7B3%7D%20%5C%20%20m%2Fs)
=> ![KE_e = \frac{1}{2} * m * (11.3 *10^{3})^2](https://tex.z-dn.net/?f=KE_e%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20%20%2A%20%20m%20%2A%20%20%2811.3%20%2A10%5E%7B3%7D%29%5E2)
=> ![KE_e = 6.272 *10^{7} \ \ m \ \ J](https://tex.z-dn.net/?f=KE_e%20%3D%20%206.272%20%2A10%5E%7B7%7D%20%5C%20%20%5C%20%20m%20%20%5C%20%5C%20%20%20J)
Generally given that at a position that is very far from the earth that the is Zero, the kinetic energy at that position is mathematically represented as
![KE_p = \frac{1}{2} * m * v^2](https://tex.z-dn.net/?f=KE_p%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20%20%2A%20%20m%20%2A%20%20v%5E2)
Generally from the law energy conservation we have that
So
![2.101 *10^{8} m + 6.272 *10^{7} m = \frac{1}{2} * m * v^2](https://tex.z-dn.net/?f=2.101%20%2A10%5E%7B8%7D%20%20m%20%20%2B%20%206.272%20%2A10%5E%7B7%7D%20%20m%20%20%3D%20%20%20%5Cfrac%7B1%7D%7B2%7D%20%20%2A%20%20m%20%2A%20%20v%5E2)
=> ![5.4564 *10^{8} = v^2](https://tex.z-dn.net/?f=5.4564%20%2A10%5E%7B8%7D%20%3D%20%20%20v%5E2)
=> ![v = \sqrt{5.4564 *10^{8}}](https://tex.z-dn.net/?f=v%20%3D%20%20%5Csqrt%7B5.4564%20%2A10%5E%7B8%7D%7D)
=> ![v = 2.3359 *10^{4} \ m/s](https://tex.z-dn.net/?f=v%20%20%3D%20%202.3359%20%2A10%5E%7B4%7D%20%5C%20m%2Fs)
Answer:
Alburt Bandura
Explanation:
Rosalind has learned to be impulsive and seldom waits for her turn when playing with other children, this trait she has learned from her father, who is also an impulsive man.
The theorist who would most likely suggest that Rosalind has learned to be impulsive from watching her father is Alburt Bandura. Alburt in his famous Bebo Doll experiment confirmed that children learn from the adults behavior in their life.
Objects will accelerate more by 10 (m/s)2
Answer:
Frictional force always acts parallel to two planes in contact with each other and in a direction opposite to that of relative motion of the two bodies. 2. Frictional forces are caused due to intermolecular interactions between the bodies. Frictional force is more for rough surface and less for smooth surfaces.
