If a projectile is shot at a velocity of #6 m/s# and an angle of #pi/4#, how far will the projectile travel before landing?
1 Answer
Explanation:
Let the velocity of projection of the projectile be u with angle of projection
The vertical component of the velocity of projection is
Now if the time of flight be T then the object will return to the ground after T sec and during this T sec its total vertical dosplacement h will be zero. So applying the
equation of motion under gravity we can write
The horizontal displacement during this T sec is
In the given problem
So the distance travaresed by the projectile before landing is
