Question

@Abhisar
A stationary object is released from the point P with 3R from the centre of the moon of radius R and mass m.Find an expression in terms of G,m and R for the speed of the object when it hits the moon's surface.

Answer 1

easyyyyy

Answer 2

give me a minute.....i will give you a formula to your answer

Answer 3

ok...thanks...

Answer 4

\[K.E =Force * distance\]
\[\frac{ 1 }{ 2 }*mass*v^{2} = G \frac{ Moon*mass }{ radius }\]

Answer 5

Solve for v (velocity)

Answer 6

That is your answer

Answer 7

Gravitational Force = \(\huge \frac{Gmm_o}{r^2}\\=>acceleratio~due~to~gravity=\huge \frac{Gm}{r^2}\)

Answer 8

Now substitute the value of r as 3r and find acceleration

Answer 9

Then use \(V^2=U^2+2as\) to find V,
Take u=0
s=3r-r=2r

Answer 10

damnnnn....... you smart.

Answer 11

Thank you very much...
