Question

A shell is fired from a canon with velocity v m/s at an angle

Answer 1

may be at a angle of 45° since it is the by whoch the object will travel farthest therefore shell will be fired at a angle of 45 according to conditions

Answer 2

$\huge\bf{Answer:-}$

Let y be the mass

$vcosθ$ = is the speed of one piece

Let v be the speed of other piece

Conservation of momentum

$mvθ2$=$m/2v$$θ+$$m/2v$

Hence, $v° = 3vcosθ$
