In a perfectly inelastic one-dimensional collision between two moving objects, what condition alone is necessary so that the final kinetic energy of the system is zero after the collision? (a) The objects must have initial momenta with the same magnitude but opposite directions. (b) The objectsmust have the same mass. (c) The objects must have the same initial velocity.(d) The objects must have the same initial speed, with velocity vectors inopposite directions.

Marble A was released at a certain height of the ramp and hit Marble B on the horizontal end of the ramp. Both Marbles A and B weighs 5 grams. The horizontal distances covered by marbles A and B after the collision are 5 cm and 35 cm, respectively. The elevation from the edge of the ramp to the ground is 15cm. Assuming that energy and momentum are conserved, what is initial potential energy (in erg; erg = dyne.cm) of Marble A? Use g=980cm/s2. Round off your answer to two decimal places.  Answer correctly, thank you.

a particle of mass .260kg moves head on with a velocity .534x+.374y m/s toward a second particle of mass .486 kg placed on a smooth horizontal table. here x and y are unit vectors along the x and y axis. the collison is completely inelastic. the energy lost in this collision is?

Consider the two pucks shown in the figure. As they move towards each other, the momentum of each puck is equal in magnitude and opposite in direction. Given that v; oreen = 12.0 m/s, and mblue is 25.0% greater than mareen, what are the final speeds of each puck (in m/s), if - the kinetic energy of the system is converted to internal energy? 30.0 30.0 Vgreen m/s V blue m/s
