A projectile is shot from the ground at a velocity of #8 m/s# and at an angle of #(2pi)/3#. How long will it take for the projectile to land?
In y axis,
At maximum height,
Applying first equation of motion,
So, time taken in reaching maximum height is 0.692 s.Time taken for projectile to fall from maximum height to ground is also 0.692s.
