Answer:
22m/s
Explanation:
Mass, m=60 kg
Force constant, k=1300N/m
Restoring force, Fx=6500 N
Average friction force, f=50 N
Length of barrel, l=5m
y=2.5 m
Initial velocity, u=0

Substitute the values

m
Work done due to friction force

We have 
Substitute the values


Initial kinetic energy, Ki=0
Initial gravitational energy,
\
Initial elastic potential energy


Final elastic energy,
Final kinetic energy, 
Final gravitational energy, 
Final gravitational energy, 
Using work-energy theorem

Substitute the values






Answer:
An electric chemical cell is not always needed to have a power circuit. But every other part is.
Newtons first law states that an object will remain still or in straight line. Until acted upon some force!
