calculate the angular momentum of a projectile of mass m at time t after its projection in a vertical plane with velocity v at angle `alpha` with the horizontal.

A projectile si thrown with velocity of 50m//s towards an inclined plane from ground such that is strikes the inclined plane perpendiclularly. The angle of projection of the projectile is 53^(@) with the horizontal and the inclined plane is inclined at an angle of 45^(@) to the horizontal. (a) Find the time of flight. (b) Find the distance between the point of projection and the foot of inclined plane.

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 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 projected with a speed of 40m/s at a angle theta with horizontal such that tantheta=(3)/(4) . After 2 sec, the projectile is moving with speed v at an angle alpha with horizontal then, (g=10m//s^(2))
