A projectile projected from the ground has its direction of motion making an angle π4 with the horizontal at a height 40 m. If initial velocity of projection is 50 m/s, the angle of projection is (take g=10 ms−2)
A particle is projected from a point O with a velocity u in a direction making an angle α upward with the horizontal. After some time at point P it is moving at right angle with its initial direction of projection. The time of flight from O to P is
The velocity at maximum height of a projectile is half of its initial velocity of projection. the angle of projection is
A particle of mass m is projected with a velocity v making an angle 45 degree with the horizontal. The magnitude of the angular momentum of the projectile about the pointof projection when the particle is at its max height h.
