Athin uniform rectangular plate (lamina) is of mass m and dimensions 2a by a. choose a coordinate system oxyz such that the plate lies in the xy plane with origin at a corner, the long dimension being along the x-axis. find the following: (a) the moment of inertia tensor about the origin (b) the principal moments of inertia about the origin (c) the angular momentum about the origin if the plate is spinning with angular rate about the diagonal through the origin cottcides wnth he 0in rehret to an ineria frame of wich the onigin coincides with the oxyz system.

    m₁v₁ + m₂v₂ = (m₁ + m₂)vmomentum is conserved.the left-hand side of the equation represents the momentum in the system before the collision.the right-hand side represents the momentum in the system after the collisionm₁ and v₁ represents the mass and the velocity of the physics blockm₂ and v₂ represents the mass and velocity of the ball of puttyv represents the final velocity of the combined mass.the question states the two masses stick together. they combined mass has its own velocity with the body mass the sum of the two objects' massestheir combined momentum is (m₁ + m₂)vto find the magitude of (m₁ + m₂)v, we need to add the vectors on the left-hand side of the equation: m₁v₁ + m₂v₂.note the diagram. i have positioned the vectors in accordance with their directions.the magnitude of the resultant can be calculated using the pythagorean theorem since this is a right triangle situation (north and west are perpendicular)|(m₁ + m₂)v| =  √[ (m₁v₁)² + (m₂v₂)² ]|(m₁ + m₂)v| =  √[ (1.5kg·8.0m/s)² + (0.40kg·20m/s)² ]|(m₁ + m₂)v| =  14.4 kg m/sfor two significant figures (assuming that 20m/s is two), this rounds to 14 kg m/s

Ithink the answer is fusion 

The upward force acting on the wing of a airplane in flight is known as the "lift" force. (d)
