Now that we know the velocity of the cart before the collision is 1.80m/s, let’s use this to determine the linear momentum and kinetic energy of the disk-cart system before the collision. The mass of the cart is 23.5kg. The mass of the disk is 11.4kg. Using this mass information and the velocity calculated, determine the horizontal component of momentum of the disk-cart system during this interval.
