A mortar fires a projectile at an angle of 60° with the horizontal with a muzzle velocity of 200 fps. An enemy is advancing directly towards the position of the mortar on a level ground at an average speed of 20 fps. What should be the distance of the tank from the mortar at the instant the mortar is fired in order to hit the tank.

Concept explainers

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Question

. A mortar fires a projectile at an angle of 60° with the horizontal with a muzzle velocity of
200 fps. An enemy is advancing directly towards the position of the mortar on a level
ground at an average speed of 20 fps. What should be the distance of the tank from the
mortar at the instant the mortar is fired in order to hit the tank.
