22. Magnitude of force

A bullet of mass 23 \(g\) travelling horizontally with a velocity of 170$m{s}^{-1}$ strikes a stationary wooden block and comes to rest in  0.05 \(s\).

 

Calculate the distance of penetration of the bullet into the block. Also calculate the magnitude of the force exerted by the wooden block on the bullet. [Enter the values up to two decimal places]

 

Answers:

 

1. Distance of penetration of the bullet into the block \(=\)  \(m\)

 

2. Magnitude of the force exerted by the wooden block on the bullet \(=\)  \(N\)
