Question

In the figure shown a particle of mass m moving with velocity v strike a wall ( mass is infinitely large) moving towards the particle with same speed The work done on the particle during collision is

  1. fraction numerator 3 over denominator 2 end fraction m v to the power of 2 end exponent    
  2. m v to the power of 2 end exponent    
  3. 4 m v to the power of 2 end exponent    
  4. 3 m v to the power of 2 end exponent    

The correct answer is: 4 m v to the power of 2 end exponent


    Change in kinetic energy = work done
