Answer: 5 m/s
Explanation:
Momentum = mv (mass*velocity)
60kg*m/s = (12kg)*(v)
v = (60kg*m/s)/(12kg)
v = 5 m/s
Answer:B
Explanation:
Given
Distance of astronaut From asteroid x is 
Distance of astronaut From asteroid Y is 
Suppose M,M_x,M_y be the masses of Astronaut , asteroid X and Y
If the astronaut is in equilibrium then net gravitational force on it is zero
cancel out the common terms we get
