A PARTICLE OF MASS M IS SHOT WITH an initial velocity v making an angle b with the horizontal,the particle moves in the gravitational field of the earth. find the angular momentum of the particle about the origin when the particle is at the origin ,at the highest point of its trajectory, just before it hits the ground and what torque causes its angular momentum to change?
