Question 3

The depth of penetration of a research projectile into a block of uniform ballistic gel is directly proportional to its initial kinetic energy.

The projectile is fired at a speed of 150 m s-1 and penetrates to a depth of 9.0 cm.

What is the depth of penetration of the projectile, under the same conditions, when its initial speed is 250 m s-1?
