Question

A projectile is fired from ground with velocity u at an angle with the horizontal. It

would be moving perpendicular to its initial direction of projection after a time t equal to​

Answer 1

ucoseca/g where a is the angle of projection

Answer 2

HERE COMES THE ANS:-⏩⏩

PROJECTILE MOTION:-

MOTION OF OBJECT IN TWO AXISES

HORIZONTAL

VERTICAL

➡⏩⏩⏩ AS WE KNOW THAT HORIZONTAL COMPONENT OF VELOCITY. REMAINS THE SAME AND NOT AFFECTED BY ANY ANGLE OF PROJECTION IT REMAINS THE SAME❗❗

⏩⏩⏩⏩⏩ COMING TO VERTICAL COMPONENT OF PROJECTION WHICH IS AFFECTED BY :-❗❗

1⃣ :- ANGLE OF PROJECTION❗

2⃣:-. TIME TAKEN BY IT TO COVER DISTANCE ❗

3⃣ :- THE GRAVITATIONAL FORCE ❗❗❗

AS IN QUESTION WE ARE ASKED:-❗❗

AS AN OBJECT MOVES IN UPWARED DIRCTION MEANS:-

✳ HORIZONTAL DISTANCE SAME THROUGH OUT THE MOTION❗

✳ VERTICAL MOTION CHANGES WITH THE CHANGE OF FECTORS WE DESCRIBED ABOVE❗

SO THE VELOCITY IS VERIED WITH THESE FECTORS AND THE FORMULA FOR TIME PERIOD FOR PROJECTILE COMES TO BE LIKE❗❗
