A machine gun is mounted on the top of a tower of height `h`. At what angle should the gun be inclined to cover a maximum range of firing on the ground below ? The muzzle speed of bullet is `150 ms^-1`. Take `g = 10 ms^-2`.

A machine gun is mounted on the top of a tower of height h=100 m. At what angle should the gun be inclined to cover a maximum range of firing on the ground below ?The muzzle speed of the bullet is u=150 m s^(-1) and g=10 m s^(-2) .

A machine gun is mounted on the top of a tower 60 m At what angle showld the gun be inclined to cver a vaximu range of firing on the groun below? The muzzle speed of the bullet is 90 ms^(-1) take g= 10 ms^(1) .

A stone is thrown from a cliff 4.2 m high . At what angle he must incline his rifle in order to cover a maximum range of firing on the ground below . Taken muzzle velocity of bullet =20m//s and g=10ms^(-2) .

A machine gun is mounted on an armored car moving with a speed of 20 ms^(-1) . The gun point against the direction of motion of car. The muzzle speed of bullet is equal to speed of sound in air i.e., 340 ms^(-1) . The time difference between bullet actually reaching and sound of firing reaching at a target 544 m away from car at the instant of firing is reaching at a target 544 m away from car at the instant of firing is

A machine gun fires a bullet of mass 40 g with a velocity 1200 ms^-1 . The man holding it can exert a maximum force of 144 N on the gun. How many bullets can be fire per second at the most?

A body is thrown horizontal from the top of a tower and strikes the ground after two seconds at angle of 45^(@) with the horizontal. Find the height of the tower and the speed with which the body was thrown. Take g = 9.8 ms^(-2) .

A gun movunted on the top of a voing truck is aimed in the backward direction at an angle of 30^@ to the vertical. If the muzzle velocity of the bullet firee from the gun is 4 ms^(-1) , then the speed of the truck that will make the bullet come out vertically is.

A bullet fired from a gun with a velocity of 140 ms^(-1) strikes the ground at the same level as the gun at a distance of 1 km. Find the angle of inclination with the horizontal at which the bullet is fixed. Take g=9.8ms^(-2) .

A machine gun fires 50-g bullets at a speed of 1000 m/s . The gunner , holding the machine in his hands , can exert an average force of 150 N against the gun . Calculate the maximum number of bullets he can fire one minute.

A bullet is fired from a gun eith a speed of 1000m/s on order to hit target 100 m away At what height above target should the gun be aimed ? (The resistance of air is negligible and g = 10 m//s^(2) )
