In an Internal Combustion Engine, the fuel is singed in the chamber or vessel. Example: Diesel or Petrol motor utilized as a part of Cars. 
The internal engine has its vitality touched off in the barrel, as 99.9% of motors today. In an External Combustion Engine, the inner working fuel is not consumed. Here the liquid is being warmed from an outer source. The fuel is warmed and extended through the interior instrument of the motor bringing about work. Eg. Steam Turbine, Steam motor Trains. An outer burning case is a steam motor where the warming procedure is done in a kettle outside the motor.

Answer:
position as a function of time is y = 0.05 × cos(9.9)t
Explanation:
given data 
mass = 5 kg
length = 10 cm = 0.1 m
displaced = 5 cm 
to find out
position as a function of time
solution
we will apply here equilibrium that is 
mass × g = k × length
put here value and find k 
k = 
k = 490 N/m
and ω is
ω = 
ω = 
ω = 9.9
so here position w.r.t  time is
y = 0.05 × cosωt 
y = 0.05 × cos(9.9)t
so position as a function of time is y = 0.05 × cos(9.9)t
