A 5 gm bullet moving at 100 m/s strikes a wooden block kept fixed. The bullet comes to rest and stops in 5cm. What is the average force (in N) experienced by the bullet ?

Answer:

500

Solution:

By the work-energy theorem, work done by the average resistive force = loss of kinetic energy

$F \times 0.05 = \frac{1}{2} \times 0.005 \times (100)^{2} = 25$ J

$F = \frac{25}{0.05} = 500$ N
