Question 1

The penetration depth of a test projectile fired into a block of ballistic clay is directly proportional to its kinetic energy just before impact.

When the projectile is fired with an initial speed of 150 m s-1, it penetrates to a depth of 18.0 cm.

What is the penetration depth of the same projectile, under identical target conditions, if its initial speed is increased to 250 m s-1?
