What is the average power output (in W) of a heart defibrillator that dissipates 435 J of energy in 10.5 ms?

The  power is  

Explanation:

From the question we are told that

   The  energy is  

    The time taken is  

Generally the the average power is  mathematically represented as

=>    

=>    

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2
