Question

what info and concept do i need to know?

Before pmv. During ??? explosion

Answer 1

The info needed to be the masses of two bodies, initial relocity of two bodies before collision. and type of collision whether it is elastic, inclastic or perfectly énelastic collision. concept required is, conservation of momentum The momentum is conserved during collision le momentum before collision is equal to momentum ofter collision. energy conservation # If collision is perfectly elastic then there would be no Loss of energy, energy before collision would be equal to energy after collision. H collision is inclastic their will be loss of energy that can be calculated by subtracting Initial and final kinetic energies. momentum of a body is given P = mo, it i u rector quantity Kinetic energy of a body is given k = + mv², it is scalar quantity.
