In a perfectly inelastic one-dimensional collision between two objects, what condition alone is necessary so that all of the original kinetic energy of the system is gone after the collision?

In a perfectly inelastic one-dimensional collision between two objects, what initial condition alone is necessary so that a the system is gone after the collision? O The objects must have momenta with the same magnitude but opposite directions. medi ume O The objects must have the same mass. O The objects must have the same velocity. O The objects must have the same speed, with velocity vectors in opposite directions. AC

In the figure, block 1 of mass m₁ slides from rest along a frictionless ramp from height h-3 m and then collides with stationary block 2, which has mass m₂ - 5m₁. After the collision, block 2 slides into a region where the coefficient of kinetic friction is 0.6 and comes to a stop in distance d within that region. What is the value of distance d if the collision is (a) elastic and (b) completely inelastic? (a) Number (b) Number i h Unit Unit Frictionless 9 -H₂

Is the following statement true? If not, why? Within the system, both the momentum and kinetic energy are conserved during each of the collisions ( spring-loaded elastic, hoop spring, and putty collisions).
