when a body is projected at an angle ` 45^@`, its range is maimum.
For maximum range, the value of ` sin 2 theta ` should be equal to one.

(A): When a body is projected at angle 45^(@) its range is maximum (R): For maximum of range, the value of sin 2 theta should be equal to one.

A body is projected at an angle theta so that its range is maximum.If T is the time of flight then the value of maximum range is (acceleration due to gravity = g )

A body is projected at an angle theta so that its range is maximum. If T is the time of flight then the value of maximum range is (acceleration due to gravity= g)

A body is projected at an angle thita so that its range is maximum . If T is the time of light , then the value of maximum range is ( acceleration due to gravity = g)

The range of a projectile at an angle theta is equal to half of the maximum range if thrown at the same speed. The angel of projection theta is given by
