Explanation:
It is given that,
Relativistic Mass of the stone, m₀ = 0.6
Mass, [tex]m=0.76\ kg[/tex]
Relativistic mass is given by :
[tex]m=\dfrac{m_o}{\sqrt{1-\dfrac{v^2}{c^2}}}[/tex].........(1)
Where
c is the speed of light
On rearranging equation (1) we get :
[tex]v^2=c^2(1-(\dfrac{m_o}{m})^2)[/tex]
[tex]v=c\sqrt{ (1-(\dfrac{m_o}{m})^2)}[/tex]
[tex]v=c\sqrt{ (1-(\dfrac{0.6}{0.76})^2)}[/tex]
v = 0.61378 c
or
v = 0.6138 c
So, the correct option is (c). Hence, this is the required solution.
