# Railguns on the roll

A railgun is a powerful weapon which is used in tanks. It shoots with a velocity of $$750\text{ m/s}$$. If the height of the tank is $$3\text{ m}$$, what is the maximum height (in metres) above the ground to which a railgun can shoot?

Details and assumptions:-

• Assume that the railgun can shoot at any angle to the horizontal.
• Neglect the air resistance
• Take the acceleration due to gravity(g) as $$10{\text{ m/s}}^2$$.
