Answer:
Explanation:
Given
mass of rock 
Elevation of Rock 
Distance traveled by rock with time
where, u=initial velocity
t=time
a=acceleration
here initial velocity is zero
when rock is 5 m from ground then it has traveled a distance of 5 m from top because total height is 10 m
velocity at this time
Answer:
