Answer:
3750
Explanation:
Kinetic energy of the bullet before it hits the wall - K1
Kinetic energy of the bullet after it hits the wall - K2
Work done by the bullet passing through the wall - W
By the conservation of energy,
1/2 x 50 x 10^-3 x 400^2 = W + 1/2 x 50 x 10^-3 x 100^2
W = 1/2 x 50 x 10^-3 x 300^2
W = 3750 J
