Assertion : In order to hit a target, a man should point his rifle in the same direction as target.
Reason : The horizontal range of the bullet is dependent on the angle of projectile with horizontal direction.

If a man wants to hit a target, he should point his rifle-

Assertion: Horizontal range is same for angle of projection theta and (90^(@)- theta) . Reason : Horizontal range is independent of angle of projection.

Assertion : In projectile motion, the angle between the instantaneous velocity and acceleration at the highest point is 180^(@) . Reason : At the highest point, velocity of projectile will be in horizontal direction only.

Show that the horizontal range of a projectile is same for two angles of projection . Is the sum of maximum heights for these two angles dependent on the angle of projectile ?

Assertion: The maximum horizontal range of projectile is proportional to square of velocity. Reason: The maximum horizontal range of projectile is equal to maximum height attained by projectile.

Define trajectory of a projectile and hence derive equation of motion of the projectile when projected at an angle theta with horizontal direction.

In the following questions a statement of assertion (A) is followed by a statement of reason ( R). A: Horizontal range of a projectile is always same for angle of projection theta with horizontal or theta with vertical . R : Horizontal range depends only on angle of projection .

Find the equation of trajectory, time of flight , maximum height and horizontal range of a projectile when projected at an angle theta with the vertical direction .

Find (a) time of flight , (b) Max.height (c ) Horizontal range of projectile projected with speed (v) making an angle theta with the horizontal direction from ground.

An object is thrown along a direction inclined at an angle of 45^(@) with the horizontal direction. The horizontal range of the particle is equal to
