A battleship has a gun that fires shells with muzzle velocity u, and the gunner wants to hit an enemy ship at range L. The gun is to be fired at some angle θ above the horizontal. Find the two possible values of θ that are possible under normal conditions. Under what conditions are there one solution or no solutions at all? To what extent is the form of the solution determined by units?
Homework Answers
If bullet will hit for any angle theta obtained by the relation
shown in picture then bullet will also hit for the angle 90-theta .
And for the angle 90 degree there will no possibility to hit the
enemy ship by bullet.

A battleship simultaneously fires two shells toward two identical enemy ships. One shell hits ship A, which is close by, and the other hits ship B, which is farther away. The two shells are fired at the same speed. Assume that air resistance is negligible and that the magnitude of the acceleration due to gravity is g. * What shape is the trajectory (graph of y vs. x) of the shells? a.straight line b.parabola c.hyperbola d. The shape cannot be...

A cannon fires a cannonball with muzzle velocity vo (muzzle velocity is the velocity at which the projectile leaves the cannon). The maximum range of the cannon is 17.6 km (a) What is the muzzle velocity v? (b) A target is a horizontal distance of 5.50 km away fronm the cannon-The cannon can hit this target by firing at two different angles, a low angle 6, and a high angle 0. Calculate these two angles. (c) Find the times, t...

The shells fired from an artillery piece have a muzzle speed of 195 m/s, and the target is at a horizontal distance of 2.00 km. Two possible angles can be used to hit the target. Find the smallest angle relative to the horizontal at which the gun should be aimed? (Hint: sin2θ = 2sinθcosθ)

A warship has a gun that fires a projectile at an initial speed of 400 m/s. It fires at an enemy ship that is 10.0 km away. At what angle from the horizontal should the gun be fired in order to hit the enemy, assuming that the enemy’s location does not change? (Hint: you can write two equations involving time, one for the horizontal motion, and one for the vertical motion. Solve one equation for time and substitute into the...

A modern 5-inch 62-calibre naval gun can fire a 32 kg shell at a muzzle velocity of 800 m/s to a range of 37 km at 20 rounds/min. Suppose such a gun fires a projectile eastward at a nearly horizontal trajectory to a target 12 km away. The ship is at 60° geographic latitude. Find the deflection of the projectile due to the Coriolis force in both the northern and southern hemispheres (ignore air resistance).
