A projectile is fired at an angle of 45^(@) with the horizontal. Elevation angle of the projection at its highest point as seen from the point of projection is

A particle of mass m is projected with a velocity v making an angle of 45^@ with the horizontal. The magnitude of the angular momentum of the projectile abut the point of projection when the particle is at its maximum height h is.

A projectile is fired at an angle of 30^(@) with the horizontal such that the vertical component of its initial velocity is 80m/s. Find approximatly the velocity of the projectile at time T//4 where T is time of flight.

A ball is projected at an angle 45^(@) with horizontal. It passes through a wall of height h at horizontal distance d_(1) from the point of projection and strikes the ground at a horizontal distance (d_(1) + d_(2)) from the point of projection, then
