Using conservation of energy law:-
∑ work in = ∑ work out
and work= force* displacement
so when we wanted to move a 100kg a distance of 1m
we multiplied 100*1 = work out
so work in should be equal to 100*g Joules, where g is the acceleration due to gravity.
so workout = 100*g = 25*g *x (divide both sides by 25*g)
x=4m
by the same way:-
------------------------
work in = 100kg * 2m * g (m/
)= work out
so work out = 25*x*g = 200* g (divide both sides by 25*g)
x=8m

Answer:
48m
Explanation:
- Initial velocity = 4m/s
- Acceleration = 4m/s²
- Time = 4s
- Displacement = ?
From Second equation of motion ,
s = ut + 1/2at²
s = 4*4 + 1/2*4*(4)² m
s = (16 + 2 * 16) m
s = ( 16 + 32 )m
s = 48 m
