In an experiment on measuring the range of bullet, bullet was fired from gun at angles `30^@`, `37^@`, `42^@` and `53^@` with same muzzle speed. In which case you expect the maximum range of the bullet?
(A) `30^@`
(B) `37^@`
(C) `42^@`
(D) `53^@`

Ratio of the ranges of the bullets fired from a gun ( of constant muzzle speed ) at angle theta, 2 theta &4 theta is found in the ratio x:2:2 , then the value of x will be ( Assume same muzzle speed of bullets )

A gun fires two bullets at 60^(@) and 30^(@) with horizontal. The bullets strike at same horizontal distance. The ratio of the maximum height for the two bullets is in the ratio

Two projectiles are fired from the same point with the same speed at angles of projection 60^(@) (B) and 30^(@) (A) respectively. Which one of the following is true?

In the given figure points A and C are on the horizontal ground & A and B are in same vertical plane. Simultaneously bullets are fired from A, B and C and they collide at D. The bullet at B is fired horizontally with speed of 72/5 km//hr and the bullet at C is projected vertically upward at velocity of 54/5 km//hr . Find velocity of the bullet projected from A in m//s .

Three particles A, B and C are projected from the same point with the same initial speeds making angles 30^(@), 45^(@) and 60^(@) respectively with the horizontal. Which of the following statement is correct?

A gun of mass M(including the carriage) fires a shot of mass m . The gun along with the carriage is kept on a smooth horizontal surface. The muzzle speed of the bullet v_r is constant. Find (a) The elevation of the gun with horizontal at which maximum range of bullet with respect to the ground is obtained. (b) The maximum range of the bullet.

An artillary piece which consistently shoots its shells with the same muzzle speed has a maximum range R. To hit a target which is R//2 from the gun and on the same level, the elevation angle of the gun should be

A trajectory of a fighter plane is given by the relation y = x + c (when and y represents horizontal and vertical axes). The plane is moving with a constant speed of 30sqrt2 m//s . A machine gun is mounted on the plane. When the plane is at a height of 240m from the ground, a bullet is fired from the machine-gun with a speed of 10 m/s with respect to the plane in the vertical upward direction. (a) Calculate the time after which it will hit the ground (b) Find the maximum height reached by the bullet.

A student performs an experiment to determine how the range of a ball depends on the velocity with which it is projected. The "range" is the distance between the points where the ball lends and from where it was projected, assuming it lands at the same height from which it was projected. It each trial, the student uses the same baseball, and launches it at the same angle. Table shows the experimental results. |{:("Trail","Launch speed" (m//s),"Range"(m)),(1,10,8),(2,20,31.8),(3,30,70.7),(4,40,122.5):}| Based on this data, the student then hypothesizes that the range, R, depends on the initial speed v_(0) according to the following equation : R=Cv_(0)^(n) , where C is a constant and n is another constant. The student performs another trial in which the ball is launched at speed 5.0 m//s . Its range is approximately:
